14-> ''"Industrial Grade Nano-Paste, Planet's most valuable commodity, can also be one of its most dangerous. Simply pour out several canisters, slide in a programming transponder, and step well away while the stuff cooks. In under an hour the nano will use available materials to assemble a small factory, a hovertank, or enough impact rifles to equip a regiment."''

19In [[GratuitousLatin Latin]], ''nanus'' means "dwarf." In science, the prefix ''nano-'' means "one billionth" of something. [[http://en.wikipedia.org/wiki/Nanotechnology Nanotechnology]] is technology on a scale of 1-100 nanometers (1 nanometer being one billionth of a meter).
20
21Nanotechnology has become an all-purpose [[AWizardDidIt magic]] substitute for soft science fiction and sci-fi-flavored fantasy. Nano is the latest {{Sci Fi Name Buzzword|s}}; it is the new pseudo-Greek for [[PhlebotinumDuJour phlebotinum]]. Nanotech supplies a myriad of exciting powers with a satisfying patina of plausibility.
22
23As a result, Nanobots lead to interesting plots and settings even in otherwise hard science fiction. After all, if one could make a tiny robot at the nanometer scale[[note]]A hydrogen atom is about 0.1 nanometers across, visible light has a wavelength of 400-800 nanometers and a human hair is about 100,000 nanometers wide[[/note]] and that little robot created another, and those two robots made four...
24
25Once you have a vast mass of these robots, all ready to accept orders and shuffle stuff around at the molecular level, they can potentially do anything nature does and much, much more. Real-life nanomachine research is being done in areas such as medicine, manufacturing, and chemical engineering.
26
27More often, fiction delights in taking nanotech way, way beyond the plausible. Nanomachines, "nanites" or "nanobots" [[PhlebotinumDuJour are a writer's best friend]]. Writers are not expected to ''show'' the nanomachines doing whatever it is that they do, all they have to do are the results. And the results can be ''anything''. Nanomachines can be depicted as masses of cloud/liquid in external "colonies", VoluntaryShapeshifting {{Blob|Monster}}s, or syringes of ''stuff'' to be injected into humans and have [[SuperSerum fantastic]] [[{{Transhuman}} results]], usually in the form of [[JustForFun/HowToGiveACharacterSuperpowers superpowers]], but sometimes in the form of a ForcedTransformation, UnwillingRoboticisation or HarmfulHealing.
28
29Real-life physics, however, puts constraints on what nanomachines can accomplish. For starters, without some source of energy, they will just sit there being molecules, or at best work veeeery slowly using ambient energy. Besides that, there's the issue of heat. The basic laws of thermodynamics state that there is no machine that can convert energy into work with 100% efficiency (I.E. without losing any energy in the form of heat), and the SquareCubeLaw states that many small machines have ''a lot'' more surface area through which heat can leak out as opposed to one big machine. If you put two and two together, it means that any swarm of nanomachines is at the constant threat of building up enough heat to cook its fragile components. Finally, there's also the so-called "sticky fingers" problem that quantum-sized particles simply ''don't act'' like macroscopic matter, such that simply picking them up, moving them, and (most of all) ''putting them down again'' is a much, ''much'' thornier problem than is popularly understood. But most writers rarely study the subject in any detail; it's easier to just use them as GreenRocks that can do anything the plot requires.
30
31One reasonably common science-fiction scenario involves nanomachines being programmed to build copies of themselves using materials in their environment. If not stopped, such nanobots could theoretically grow exponentially, turning all available material on Earth into more nanobots and ending life as we know it -- this is known as the "GreyGoo" scenario. Some scientists have expressed concern that this scenario could actually happen in real life, although most consider it extremely [[http://nanotechweb.org/cws/article/indepth/19648 unlikely]] to be accidentally built.
32
33Because it is so powerful, in settings where science is ''inherently'' bad, expect nanotech to be way up there on the ScaleOfScientificSins.
34
35Nanotech is a fairly common cause for the drastic scenario called TheSingularity. The concepts of supply and demand change utterly when humanity becomes capable of mass-producing machinery that can turn anything into anything, ensuring supply is as close to infinite as is possible. And our basic nature is thrown up into the air once we direct nanites to work on ''us''.
36
37Nanites themselves will usually either be [[SlidingScaleOfRobotIntelligence dumb as bricks]], or [[HiveMind networked into a fully sentient mass]]. Some works may invoke MechanicalEvolution to make the nanomachines smarter/better/deadlier. Scale them up a bit and you've got a MicrobotSwarm.
38
39An important note, though: While many of the listed examples, and indeed fiction in general, may lead you to think otherwise, nanotechnology does '''not''' only involve nanomachines. Nanotechnology is simply any kind of technology that operates on the scale of atoms. This can be about anything, like making surfaces waterproof, increasing the surface contact for faster (chemical) reactions, or using silver nanoparticles as antibacterial component.

54[[folder:ComicBooks]]
55* ''ComicBook/TheAuthority'': Authority member The Engineer replaced all of her blood with nanomachines. She can [[ImaginationBasedSuperpower create nearly anything with these]], from {{Arm Cannon}}s to [[MesACrowd duplicates of herself]]. This being ''The Authority'', many of the implications of these powers are investigated.
56* In Adam Warren's version of the ''Literature/DirtyPair'', nanotechnology is strictly regulated to the point of being outlawed, after a GreyGoo outbreak called the "Nanoclysm" [[EarthThatWas destroyed the Earth]] years ago. One villain uses nanobots to grant himself a HealingFactor; the Angels beat him up so much that the waste heat from the repairs does as much damage as the beating.
57* The villain's tech in the ''ComicBook/DoctorWhoTitan'' Third Doctor miniseries, although in keeping with the 1970s setting (and the Doctor's avoidance of providing too much future knowledge to UNIT), the word itself is never used, the closest being "micro-machines".
58* ''ComicBook/TheFlash'': Flash's enemy Abra Kadabra is a time traveler who [[MagicFromTechnology uses technology to simulate magic]]. At least one story describes most of his tricks as being based on nanotech.
59* ''ComicBook/IronMan'': Tony Stark once killed [[YellowPeril the Mandarin]] with nanomachines. His Extremis and Bleeding Edge armors are made out of nanomachines, while his original armor was powered by "tiny transistors," the predecessor to today's nanomachines in terms of function and origin.
60* The magic behind virtual reality in ''ComicBook/Kimmie66''.
61* During Creator/GrantMorrison's ''ComicBook/NewXMen'' run, Cassandra Nova attacks the team on a cellular level with nanosentinels.
62* In ''ComicBook/SonicTheHedgehogArchieComics'', some of Eggman's creations resulted in a hivemind mass of nanites that collected into a "city" in the forest. When an AI system of Eggman's was eliminated, NICOLE, the AI from Sally's computer, took over the dormant nanites herself and reconfigured them into a modified replica of Mobotropolis, giving her friends a new home. Nicole has been shown to occasionally modify the city structure through the nanites, though if her attention is divided, she may have trouble maintaining everything at once. NICOLE also occasionally uses those nanites to create a physical form for herself, though she just as often uses holograms instead.
63* In the fourth volume of ''ComicBook/TeenageMutantNinjaTurtlesMirage'', it is revealed that Baxter Stockman had infected April O'Neil with "[=NanoBaxterBots=]," which were slowly killing her. As a response, utrom Glurin and Professor Honeycutt devise [=NanoTurtleBots=], nanomachines that draw their fighting skills from the turtles' memories, which they then insert into April.
64* ''ComicBook/{{Transmetropolitan}}'':
65** In this setting, "Makers", which use nanomachines to create food, clothing, and most other necessities, are commonplace. Spider Jerusalem sarcastically reminisces about his youth, where virtually everything he ate, wore or owned was made from reprocessed lizard.
66** One filler issue has an interview with a man who lost his legs stopping a GreyGoo outbreak -- and who was then fired for not following the standard procedure of letting Blue Goo devour the entire endangered block and everyone still in it.
67** There's also the foglets, who are people who [[BrainUploading download their consciousness]] into a cloud of utility fog. Notably, the first story to feature this concept also features a fog person spontaneously assembling a flower out of... air? His own particles? Nanotech can't transmute elements or create mass, so it isn't clear where it came from or what it's supposed to be made of.
68* The ''ComicBook/UltimateMarvel'' universe's [[spoiler:mutant gene]] is revealed to be these in ''ComicBook/UltimateOrigins'' via a mixture of Nick Fury's blood and Wolverine's DNA.
69* Creator/ValiantComics and the then-successor Acclaim Comics have multiple nanite-powered heroes. ComicBook/{{Bloodshot}} has nanite-infused blood that, in the Valiant incarnation, survives as the "Blood of Heroes" well into the 41st century. Acclaim's Bloodshot's nanites may not be that long-lived but are capable of healing any injury [[spoiler:(provided that they have enough raw material to work with)]], reshaping his appearance, and [[SugarWiki/MomentofAwesome making a modem jack in his neck for free internet access]]. Acclaim's version of ComicBook/MagnusRobotFighter is never explicitly stated to have nanites, but his blood is metallic and capable of healing wounds, so you do the math.
70* ''ComicBook/{{Xombi}}'' is about a scientist who becomes a superhero after being injected with a nanomachine "virus" that's [[HealingFactor capable of extensive tissue regeneration]].
71[[/folder]]
72
73[[folder:Eastern European Animation]]
74* ''Animation/PinCode'': In appropriately titled episode "[=NanoBots=]", Dokko, Carlin, and Pin create many microscopic versions of The Iron Nanny. They are sent inside Wally's body, where they fight off bacteria and viruses.
75[[/folder]]
76
77[[folder:Fan Works]]
78* In the ''Franchise/HarryPotter'' fic ''[[http://fanfic.potterheadsanonymous.com/viewstory.php?sid=65&ageconsent=ok&warning=4 Draco Malfoy and the Sins of the Father,]]'' Draco tried to commit suicide after his mother was raped and killed as a punishment for his father's foul-ups, but was saved and transported to St. Mungo's where he was faced with becoming a quadruple amputee. Rather than have a crippled heir, his father had nanomachines injected into him, making him stronger, smarter and utterly incapable of committing permanent self-harm.
79* In the VisualNovel/{{Clannad}} fanfic ''Fanfic/AnEndToAllThings'', it's explicitly stated that Okazaki has these in his blood for body maintenance purposes, although they can also be used for making an AbsurdlySharpBlade.
80* ''Fanfic/{{Kitsune}}'': Mentioned in Chapter 17, used for TamperingWithFoodAndDrink, and basically creating a [[spoiler:MindControlDevice out of a radio broadcasting a signal into the bots of those who drank the tampered stuff]].
81* Volcano in ''Fanfic/MyHeroAcademiaUnchainedPredator'' has alongside his canon Eruption Quirk, a nanomachine-based Quirk gifted to him by All for One, allowing him to dismantle Izuku's Full Gauntlet with effortless ease. Against the Doom Slayer's armor, the nanomachines are rendered useless due to the temperature of the Slayer's suit being hotter than lava, with any attempt to touch it resulting in the nanomachine being incinerated.
82* Gigan in ''Fanfic/TheNewAgeOfMonsters'' is partially made out of self-repairing nanometal. The JSDF later use recovered samples to built Mechagodzilla III
83* The villain in ''Fanfic/ShadowchasersConspiracy'' uses a special {{Magitek}} variant of nanomachines as a primary weapon that acts as both a computer virus and a regular virus, able to spread from one to the other with equal ease. The limits of their powers are not yet revealed, but one doctor claims that an outbreak of them could combine the worst aspects of a MillenniumBug and Literature/TheAndromedaStrain combined. ("To use a rather trite analogy", he adds.) Jalal explains what a GreyGoo scenario is (with rather graphic accuracy) simply to scare an infected victim into taking it seriously when she doubts how dangerous it is.
84[[/folder]]
85
86[[folder:Films -- Animated]]
87* The plot of ''Anime/CowboyBebopKnockinOnHeavensDoor'' centers on these devices, which it frames as proteins that [[spoiler:make its victims see thousands of [[ButterflyOfDeathAndRebirth butterflies]] before asphyxiating them nearly instantly]].
88* In ''Anime/LupinIIIDeadOrAlive'', nanomachines were left to guard Drifting Island (where the nation's treasury is kept) against thieves, and it has proven very effective, defeating Lupin's attempts to gain access twice before General Headhunter brought Olèander to blackmail Pannish. The nanomachines operate as a smart BoobyTrap, chasing people and killing them.
89[[/folder]]
90
91[[folder:Films -- Live-Action]]
92* The MacGuffin in ''Film/BallisticEcksVsSever'' is nanotech used as an assassination weapon. Creator/RogerEbert wrote in his review: "A miniaturized assassination robot small enough to slip through the bloodstream would cost how much? Millions? And it is delivered by dart? How is this for an idea: use a poison dart, and spend the surplus on school lunches."
93* The main villains of ''Film/Ben10AlienSwarm'' are a HiveMind swarm of alien nanite-like chips capable of infecting and controlling any living creature. They even have a HiveQueen. They aren't actually nanomachines, though, more like living microchips -- "nano" just sounds cooler. Interestingly, they're initially inert, but [[spoiler:this is a ploy by the queen to keep the heroes guessing while she prepares an invasion]].
94* In the movie ''Bombshell'', a KidnappedScientist has his kidney removed and replaced with a sack of protein which is slowly being turned into a bomb by the nanomachines which he was developing.
95* In ''Film/TheDayTheEarthStoodStill2008'', nano-insects (GreyGoo-style) are used in an attempt to [[spoiler:KillAllHumans]].
96* ''Film/GIJoeTheRiseOfCobra'' features the nanites, originally created for medical intents and later weaponized (sometimes ''with medical intents'') for creating SuperSoldier EliteMooks who have a minor HealingFactor and [[BrainwashedAndCrazy parts of their brains destroyed to become fearless]].
97* Nanomachines are used in ''Film/IRobot'' to "execute" problem robots.
98* ''Film/JamesBond'':
99** In ''Film/{{Spectre}}'', Bond gets injected with the "Smart Blood", nanomachines that allow Q to track him down by satellite.
100** In ''Film/NoTimeToDie'', Dr. Valdo Obruchev has created "Heracles", a deadly mix of nanomachines and virus that spreads via touch and instantly kills its genetically coded targets. These stay in the body on an infected person forever. Also, Nomi gets injected with the "Smart Blood" as well.
101* When used as directed, the nanobots on the salvage ship in ''Film/JasonX'' can heal wounds and restore tissue damaged by cryogenic freezing. If malfunctioning, they can be used to rebuild a shot-to-living-hell psycho killer into a NighInvulnerable cyborg.
102* The source of KITT's superpowers in the 2008 ''Series/KnightRider'' PilotMovie. It's even what keeps the armor together; when the computer is turned off, the car's an ordinary non-[[ImmuneToBullets bulletproof]] ProductPlacement... er, Mustang.
103* ''Franchise/MarvelCinematicUniverse'':
104** In ''Film/BlackPanther2018'', T'Challa's sister Shuri provides him with a nanotech Panther Habit. Not only can it be stored in a necklace and [[InstantArmor deploy at a moment's notice]], but the nanites can absorb kinetic energy from attacks and then release it.
105** In ''Film/AvengersInfinityWar'', Tony Stark's new Iron Man suit is made entirely out of nanites, which not only allows him to suit up at will, but also allows him a measure of HyperspaceArsenal by converting nanites seamlessly into a wide array of energy, explosive, and even melee weapons. Peter Parker's new Spider-Man suit, which he gains before he and Stark travel to space, is similarly made of nanites that allow him to create four spider-like legs which he can use very creatively. Tony also uses the nanites to heal himself by spraying them onto open wounds.
106** For lack of an extraterrestrial giant dwarf who forges mystical weapons, ''Film/AvengersEndgame'' sees Tony [[spoiler:create his own synthetic Infinity Gauntlet using nanomachines to secure the Infinity Stones. This also plays into the movie's climactic moment when the future-displaced Thanos, thinking that he has Tony's nano-Gauntlet, attempts a new snap and discovers that the Gauntlet is empty. Instead, Tony commands his nanomachines to bring the Stones to him so he can perform his own snap and eliminate Thanos and his army. Unfortunately, the nanomachines cannot redirect the unfathomable effects of the Stones' immense celestial power and Tony's action results in his HeroicSacrifice]].
107** ''Film/SpiderManNoWayHome'' has Spidey using the wearable nanomachines to subdue an adversary: Doctor Octopus is removing swathes of the suit when he attacks, so Peter orders the nanobots stuck in the tentacles to immobilize them and effectively keep Doc Ock nailed to the ground.
108* One of the plots in the unproduced ''ComicBook/PlasticMan'' movie explained the technology which gave the titular character's powers. [[spoiler:It involves the use of an experimental chemical liquid that rubberized anything that comes in contact with... but to stabilize the transformation, the test subject has to have a nanomachine (inside its body) as a catalyst to render the liquid product safe in its organism. If the nanomachine isn't used in the process, the liquid continues to rubberize the subject until it decomposes from the liquid's GreyGoo attributes. According to the script's text, it described the nanomachine that it has the shape of a snowflake.]]
109* ''Film/StarTrekFirstContact'' marks the first time that the Borg are shown using nanotech as an assimilation tool (see [[Nanomachines/LiveActionTV the Live-Action TV page]]).
110* ''Franchise/{{Terminator}}'':
111** The T-X from ''Film/Terminator3RiseOfTheMachines'' has nanomachines among the features of her [[SwissArmyAppendage versatile arm]], which are used for some MagicalComputer effects -- the nanobots infect other machines and allow the "Terminatrix" to control them.
112** The T-3000 in ''Film/TerminatorGenisys'' takes it a step further. It is made completely out of nanomachines (dubbed "machine phase matter" in the film) that have [[spoiler:[[UnwillingRoboticisation infected and converted a human subject]], in this case John Connor himself]].
113%%* A major part of Caster's plan in ''Film/{{Transcendence}}''.%%Administrivia/ZeroContextExample
114* ''Film/TransformersFilmSeries'': According to [[AllThereInTheManual The Official Movie Guide]], Protoforms are made up of densely packed nanomachines. This is the semi-official HandWave for any transformation "cheats" in the films and where, for example, the rubber for Optimus' tires comes from.
115* In ''Film/{{Virtuosity}}'', an evil A.I. named Sid 6.7 enters the real life by creating itself an avatar using nanotech. He/It [[AppendageAssimilation absorbs glass to heal]].
116[[/folder]]
117
118[[folder:Manhua]]
119* ''Manhua/SchoolShock'': Pretty much the reason why a Vanguard is a [[SuperSoldier superior fighter]] against... soldiers, tanks, spider tanks and helicopters. Somehow, they make them super strong, fast, agile et cetera. They are also, however, harmful to the body, which is why Vanguards of the newer generations are euthanized after a certain period of time, being a military asset and damn expensive. A bunch of little machines pushing you to your limits, possibly straining the immune system, wearing you down... yep, sounds like {{Deconstruction}}.

123* Nanobots are the subject of the appropriately titled Music/TheyMightBeGiants song [[ExactlyWhatItSaysOnTheTin "Nanobots"]].
124[[/folder]]
125
126[[folder:Tabletop Games]]
127* In Eden Games' ''TabletopGame/ConspiracyX'' supplement ''Atlantis Rising'', the Atlanteans (immortal aliens) use nanotechnology for everything, including altering themselves.
128* ''TabletopGame/{{Cyberpunk}} 2020'' has a variety of nanotech, to go along with its various cyberware. Things get more interesting in ''Cybergeneration'', its sequel. ''Cybergeneration'' introduces the 'Carbon Plague,' a nanite-based disease of uncertain origin. (How uncertain? The writers [[LyingCreator intentionally made incompatible statements to fans]]). At first, the Carbon Plague horrifically deforms and kills people, but later, [[OnlyFatalToAdults kids]], then adults, start to survive. Some of the kids aren't quite the same after, now possessing one of several super-powers; morphing limbs, wireless net-hacking, electrical blasts, pseudo-telepathy (via brainwave scanning), matter manipulation, or whatever power a GameMaster can figure out a way to justify with the little [[{{Unobtainium}} hexite]]-manufacturing and manipulating nanobots that is the Carbon Plague.
129* Ubiquitous in ''TabletopGame/EclipsePhase''. [[MatterReplicator Nanofabricators]] are used to produce most goods, nanoware (most healing medichines) are an entire category of implants, and non-self-replicating nanoswarms are used for a variety of purposes. The TITANS also made frequent use of sentient GreyGoo.
130* ''TabletopGame/{{GURPS}}'' tech level progression is explicitly based on the idea that nanotechnology will take off between [=TL9 and TL10.=]
131* ''TabletopGame/MagicTheGathering'':
132** The [[AssimilationPlot Phyrexian]] "glistening oil" is heavily implied to be made from nanomachines, and so was the black cloud Yawgmoth manifested as.
133** Flowstone, the rocklike substance that made up most of the artificial world of Rath, is made of DungeonPunk-style nanomachines that can be controlled by the mind, usually by Rath's ruler, the evincar. It can be shaped into semi-sentient beasts or unleashed as a viscous tidal wave. Flowstone is not self-replicating, though; it was produced in a factory in the now-destroyed stronghold, the evincar's fortress at the center of the plane.
134* By the time of the Ninth Age shown in ''TabletopGame/{{Numenera}}'', nanotechnology has essentially integrated into every aspect of the world and become as ubiquitous as microbes; this is part of the reasoning behind how the world's scientifically powered pseudo-wizards, Nanos, can do their thing -- their "spells" just reprogram or reactivate the nanites in the surrounding area to seemingly miraculous results. The setting even includes a pseudo-GreyGoo phenomenon called the Iron Wind, in which a wave of malfunctioning nanobots swarms through an area, reconfiguring everything it encounters, with generally fatal results on living creatures.
135* Given ''TabletopGame/{{Pathfinder}}'''s dabbling with ScienceFantasy elements, nanotechnology pops up in many forms. Perhaps the most peculiar is the nanite bloodline -- sorcerers who developed their inherent magic as a result of nanotech influencing their conception and inhabiting their bodies (culminating in you becoming a nanite swarm while retaining your personality and, most of the time, appearance).
136* In ''TabletopGame/RocketAge'', the Ancient Martians had access to nanotechnology. Succession, an utterly undetectable poison created by them, is in fact a nanobot infection.
137* In ''TabletopGame/SentinelsOfTheMultiverse'', Baron Blade has a card called Repair Nanites that is a set of these. He later uses them to fake his death.
138* Nanotechnology is uncommon but exists in ''TabletopGame/{{Shadowrun}}'', or at least it did in Fourth Edition; most nanotech-built structures inexplicably collapsed at the end of Fourth Edition's metaplot, from guns to aircraft to entire office towers. Explained in Fifth Edition: artificial intelligences being held captive in the Matrix are using nanotech to break out. If they write themselves into a metahuman, they can take over the body; if they write themselves into an office tower, their efforts tend to cause it to collapse.
139* Averted in ''TabletopGame/{{Traveller}}'' except as an occasional MacGuffin. Sourcebooks explicitly state that this was done to [[RuleOfCool protect their system]].
140* ''TabletopGame/Warhammer40000'':
141** There's the Autosanguine/Black Blood implant, which injects nanobots into the bloodstream and allow someone to heal quite quickly, though it can't gloss over lost limbs or permanent scarring.
142** Virus bombs (formerly the method of choice in [[TheEndOfTheWorldAsWeKnowIt Exterminatus]]) release a virus that rapidly spreads over a planet, breaking down every last bit of living or dead organic matter into a combustible organic gruel. How it works is almost always backed up by HollywoodScience, but [[DependingOnTheAuthor one or two sources]] have taken a more logical take on the weapon, and implied that it actually delivers a payload of voracious nanobots [[GreyGoo to do their thing]].
143** Some of the novels featured a [[LivingWeapon weaponized]] nanotech swarm from the Dark Age of Technology called the Bloodtide which started out as multiple individual intellects before merging into a single mind. This being 40K, it got possessed by a daemon and went around forcing the blood out of people's bodies.
144** The Necrons possess supremely advanced nanotechnology, and some sources suggest the very "necrodermis" which makes up their bodies and most of their technology may be formed from nanomachines.
145[[/folder]]
146
147[[folder:Toys]]
148* ''Toys/{{Bionicle}}'': [[{{Pun}} Very small]] subversion; the inhabitants of [[spoiler:Mata Nui]] can be considered this. Given that [[spoiler:Mata Nui]] is a 40,000-foot tall HumongousMecha, the human-sized inhabitants who were built to maintain his systems are like nanobots to him. Also, in a more literal sense, the microscopic Rahi, Protodites, could be seen as nanobots. Zaktan's body is entirely composed of them after an unfortunate encounter with the Shadowed One.
149[[/folder]]
150
151[[folder:Webcomics]]
152* Much of Earth's technological superiority over New Abilene in ''Webcomic/AfterlifeBlues'' is based on nanotech.
153* Gavia from ''Webcomic/AliceGrove'' uses nanotechnology that lets her, among other things, levitate and create force fields.
154* ''Webcomic/AlienDice'' has healing nanites, one use ones used for repairing a particular injury, after which they deactivate, and ones that provide a permanent HealingFactor, as well as the "relays" which are nanotechnological communications devices which implant themselves in your brain, basically functioning as a form of ElectronicTelepathy.
155* ''[[http://www.littlelevers.com/Angels/ Angels and Aliens]]'' is based on a secret group of humans given nanotechnology-based abilities such as speed, strength and healing by mysterious aliens. Drawbacks include rapid depletion of energy and oxygen while using the abilities, and the one-size-fits-all female template for the transformed humans -- even if the recipient was [[GenderBender originally male]].
156* In ''Webcomic/BladeOfToshubi'', a nano-virus was used in [[WorldWarWhatever World War IV]] to rid the Earth's surface of humans and is believed to have caused [[AnimalIsTheNewMan the mutation of animals to a sentient, humanoid form]].
157* In ''Webcomic/CommanderKitty'', though they don't play a large part in the plot, [[http://www.commanderkitty.com/2012/01/01/seemed-like-a-good-idea-at-the-time/ nanomachines are brought up]] as the means of [[UnwillingRoboticisation turning a freshly made clone into a "perfect" android]].
158* At least two types of nanomachines showed up during the ''Webcomic/CrossoverWars'': mini-gnomes from ''Webcomic/MagicalMisfits'' were sent to the Evil Overlords headquarters to sabotage things, and nanite versions of ''Webcomic/{{Mindmistress}}'' were left there to monitor things.
159* Averted in ''Webcomic/{{Freefall}}''. Mark [[AllThereInTheManual has said several times]] that he avoids using nanomachines because it's become an equivalent to magic.
160* In ''Webcomic/TheGodOfHighSchool'', all of the fighters in the titular tournament are injected with nanomachines that constantly monitor their vitals and heal them between matches.
161* Played with during the "The Island and the Idol" arc in ''Webcomic/TheInexplicableAdventuresOfBob''. Bob and Voluptua are both injured. Hibachi comes to their rescue, and Jean is excited to see him spray medical nanites on their injuries... until the nanites form themselves into rather boring-looking ''casts'' around those injuries. Voluptua explains that even with the nanites helping, healing an injury takes ''time.'' Jean is still disappointed.
162* Most of the advanced Martian technology in ''Webcomic/AMiracleOfScience'' is based on nanites.
163* ''Webcomic/SchlockMercenary'': Nanomachines, generally referred to as "nannies," have been mentioned on various occasions, and several {{Story Arc}}s have featured them heavily. They vary between mil-spec soldier boosts (illegal outside the military) that increase all physical abilities, civilian strength and immune-system enhancements, and the Lazarus SuperSoldier boosts that can turn someone into a killing machine strong enough to punch through a tank, with the side effect of near-perfect immortality. Various human black ops projects spend generations trying to keep the immortality while getting rid of the SuperSoldier part, but progress was hampered by the fact that they found it incredibly useful as a secret weapon to let them put highly trained agents in the bodies of sleeper agents scattered around Terran space. [[spoiler:The main characters ultimately solve the problem practically overnight, and give immortality to everyone]].
164-->'''Dr. Bunnigus:''' The military research agency in control of the project did the only logical thing.\
165'''Breya:''' Oh let me guess... and I'm going to go with irony here: They kept it a secret "in order to save lives."\
166'''Dr. Bunnigus:''' Correct. Also, they deployed it so they could kill people.
167** The comic also acknowledges limitations on what nanomachines can do. When the mercenaries encounter potentially-hostile nannies, they immediately [[KillItWithFire kill them with fire]] - because high surface area to volume means that they burn really well.
168* Featured prominently in the ''Webcomic/SluggyFreelance'' StoryArc [[http://www.sluggy.com/daily.php?date=000101 "Kiki's Virus"]], in which nanobots turn into a deadly virus thanks to the MillenniumBug. Nanotechnology is also used by Dr. Crabtree for more outlandish, shapeshifting purposes.
169* Both used and subverted in ''Triquetra Cats''. Nanites are a miracle cure for most any medical condition however each use increases your chances of contracting a disease called NCDS (nanite cellular disintegration syndrome) where the nanite user's cells can no longer support themselves and break down.
170* In ''Webcomic/UmlautHouse 2'', nanites first appear when Sissy steals some assemblers from fellow MadScientist Dr. Lyse to build her fortress. Later, it seems that nanotech is used for home replicators and when Peggy Seus asks the Dragon what it is it tells her to "ask Dr. Lyse about foglets". [[spoiler:Now it seems that Lyse has replaced every cell in his body with foglets and the Dragon tried to take over his body.]]
171* ''Webcomic/UseSwordOnMonster'' features {{Magitek}} nanites called thaumites. In the arc they're introduced they've been hijacked by the Pax Ferus group to run wild.
172* Some of the characters in ''Webcomic/WeAreTheWyrecats'' are physically augmented with nanobots./xkcd.com/865/ about this]].
173* There is of course an ''Webcomic/{{xkcd}}'' comic [[http://xkcd.com/865/ about this]].

177* The ''Literature/ChaosTimeline'' has a lot of them in the last years.
178* The Chasti Perma Lock line of online erotic fiction features an entire manufacturing entity which produces nanite-powered devices such as chastity devices, gags and so forth by the action of nanites on a person. For example, a chastity device is made by nanites closing up the... operative... opening permanently. You can use your imagination as to the rest.
179* ''Literature/TheJournalEntries'' seem to use nanotechnology mostly for medical purposes. Pendorians owe their enhanced health and immortality to being, effectively, nanotech cyborgs, but don't exhibit much in the way of actual 'superpowers'; they're mostly depicted as regular folks with an occasionally odd-seeming outlook on things and seriously extended lifespans.
180* In ''Roleplay/LeagueOfIntergalacticCosmicChampions'', the heroes fight both an AI that uses nanites and a minor villain from the future who has nanotechnology, amongst other uses.
181* Nanotech is a big part of everyday life in ''Website/OrionsArm'', sometimes to the extent of replacing all natural microbes in an environment. [[https://orionsarm.com/eg-article/4aae1c18950ae One thing it's not very good for is combat]], unless the group using it has the element of surprise.
182* [[http://www.scp-wiki.net/scp-204 SCP-204-1]] from ''Website/SCPFoundation'' is a swarm of [[EatingMachine carnivorous]] nanobots that seeks out a human child to act as its GuardianEntity, although it turns the child into an [[EnfantTerrible aggressive sociopath]] to put into danger so that it has a means of gaining food.
183* ''Website/TaerelSetting'': The kin'toni (vampires) appear to have these in their blood: in fact, [[https://taerel.com/wiki/index.php?title=Taerel:Biology_(Kin%27toni) the article on kin'toni biology]] mentions that nanotech was used to alter hantavirus packets as part of the kin'toni virus' making. Rykintas Aughan is mentioned to of died of a heart attack after nanobots in his body turned against him.
184* In ''Roleplay/WeAreOurAvatars'', Yasmin, Izzy and anyone Izzy gives nanomachines to has a HealingFactor that comes from said nanomachines.
185* Sam Everheart is walking around in the ''Literature/WhateleyUniverse'' because Sam interrupted an attempt to steal a nanotechnology experiment and ended up getting the nanotech, which then did a whole-body alteration. Luckily, Sam survived it.
186* In ''Literature/WorldDominationInRetrospect'', the VillainProtagonist Psycho Gecko has nanites that allow him to heal from anything up to and possibly including death, as well as change his phenotype and, if necessary, go GreyGoo on his enemies.

190* It's a common mistake to conflate nano''machines'' with nano''technology''. While nanomachines of any kind -- much less the kind that can give people superpowers or destroy the planet -- are not yet feasible, nanotechnology has been in common use for a long time now.
191** Computation and data storage: this is the most widespread and time-tested use of advanced nanotechnology. [=CDs=], for one, use pits around 100nm deep for storing data. And the device you're using to read this article ''right now''? The transistors in its microchips are probably even smaller than that. They've been sub-100nm since 2002. Nowadays, transistors are around 14nm in size, which is smaller than an HIV virus.
192** Nanofactories: A small, printer-sized device which isn't limited to shooting ink onto paper ([[MundaneUtility though it could if you want it to]]). If you have the raw material for it, you could print out entire electronic integrated circuits or other complex things.
193** Nanomaterials: Super strong, very tough, and incredibly light, carbon nanomaterials. They are the FlyingBrick of materials, in a sense. Variants include nanotubes, nanobuds, graphene sheets, etc.
194** Nanomedicine: While we have no idea how to make ourselves immortal, superpowered badasses yet, doctors hope nanotechnology has the promise of eventually being able to cure the common cold. And HIV. And Cancer. The tricky part is actually getting the nanites to know what they should attack. This is being worked on mighty well. Nanites engineered to precisely exploit abnormally swollen pores in cancer tissue are in development. Ultra-tiny nanotube-based radio devices are also in development, which would allow for ''remote-controlled'' nanites, but those are somewhat farther away.
195** Non-Newtonian liquid suspensions: Basically, funny-shaped particles made by nanoengineering, floating in thick oil. Flexible when subjected to the force of human muscles, but turn ultra-rigid when compressed by something faster. Like a bullet. Body armor that can stop a rifle round and also allows one to do crunches like it wasn't there. It's basically a man-made enhancement of the forces that allow [[http://www.teachertube.com/view_video.php?viewkey=720f7702c5ab116120e0&page=1&viewtype=&category= John Tickle to walk on custard.]]
196* The self replication thing commonly associated with nanobots is being researched too with some success, though generally the better a nanobot is at self replicating, the worse it is at doing anything other than that. The reason why self replicating is so crucial is because nanobots are really tiny, so you need to build a lot of them to do just about anything on the scale required by humans. And because you need so many, the cost of each nanobot has to be tiny. To give an example, say you use nanobots to replace red blood cells. A healthy human male has 4-6 million cells per ''drop'' of blood. If your nanobots cost even one penny each, then just replacing that one drop costs at least $40,000.
197* If you think about it, nanomachines are actually much OlderThanTheyThink, since proteins are essentially naturally occurring nanomachines. They are quite small, and they can accomplish functions like [[http://en.wikipedia.org/wiki/Enzyme facilitating chemical reactions]], [[http://en.wikipedia.org/wiki/Na-K-ATPase_pump pumping substances across barriers,]] and when working together can even [[http://en.wikipedia.org/wiki/Actomyosin cause macro-scale movement]] of objects.[[note]]Without nanomachines, you wouldn't have been able to open this note. Reward them with a cup of a xanthine alkaloid. Preferably coffee.[[/note]]
198** Monoclonal antibodies ''already'' meet most of the criteria for medical nanomachines. Cultivate some that adhere to tumors, stick a radioactive isotope on each one, and turn 'em loose in the body to hunt down their prey like itty bitty Terminators.
199** Another impressive example of an existing natural nanomachine is ATP synthase, which makes both the electric motor[[note]]specifically, a proton-motive electrostatic motor, complete with armature and stator[[/note]] ''and'' the reciprocating engine.[[note]]The ATP-producing end is basically a 3-cylinder radial engine.[[/note]]
200** Another remarkable example of a natural nanomachine capable of manufacturing stuff is a ribosome. These are the things that actually assemble proteins according to their encoding in DNA/RNA and are a vital component of all natural replicators such as bacteria or eukaryotic cells. They self-assemble from their component proteins, so they can trivially replicate themselves. They're also hackable; viruses propagate by injecting their own DNA or RNA into cells, and awaiting the ribosome-based production line to unwittingly start making copies.
201** Neurons are the most basic components of the human nervous system, but they can conduct electricity. They're like highly efficient transistors, but with multiple dendrites and synapses, they each can receive, process, interpret and store a lot of data simultaneously, more than a mere silicon-based transistor can. (A silicon microchip is just composed of AND, OR and NOT transistor switches that can't adapt to anything new; a neuron is a true nanite in that it can adapt to anything it learns.) In fact, neurons can process 2.5 petabytes. Not only that, they can also produce chemicals (neurotransmitters) that allow humans to have emotions. And the human brain has ''86 billion of them'' connected to over ''100 trillion synapses'', working together in parallel-processing at 1 exaFLOP, which is equivalent to a billion billion calculations per second. This is why we even have intelligence and sentience, why we conquered the world in the first place. This is why every researcher in ArtificialIntelligence now tries to pattern their programming after human biological neurology (see also: [[https://en.wikipedia.org/wiki/Neural_network Neural Networks]]) and even Deepmind, the world's leading institute in AI, admitted that they can't compare to the power of the Human Brain, the most advanced, Nanite-based supercomputer in the entire world.
202** Given these examples, the cell is a complete nanite in the classical sense. Able to consume external resources, duplicate seemingly endlessly, store massive amounts of data (via DNA), manufacture anything on its to-do list, etc. Some of the closest stuff to grey goo is bacteria, while most large multicellular organisms are large nanite colonies with hundreds of different types of nanites working in harmony from a single instruction set to form complex machinery (organs) operating an automaton. That's right, forget {{cyborg}}s, ''[[AndThenJohnWasAZombie YOU]]'' [[BioPunk are a nanomechanical robot]].
203* This video, depicting [[https://www.youtube.com/watch?v=PYxBy_Sz3Wc claytronics.]] This is just a simulation, but it is running off actual software. Using a sort of nanobot programming language, a CAD file gets read in, and the nanobots reshape themselves to match it. The program is supposedly only a couple of pages long. For now this is just software, nothing to worry about-- but the guy who made this video thinks that he will have the hardware to do this in real life within the decade.
204* Modifying retroviruses for beneficial uses such as gene therapy can be thought of as bio-nanotechnology. A normal virus injects its DNA into a cell to hijack its protein production. The cell then starts making viruses instead, which repeat the process. A retrovirus, however, uses RNA to modify the host cell's DNA permanently. The cell may still undergo normal functions, with the addition of making viruses. This way, when the cell undergoes division, it also creates more cells with the same infected DNA. (This is partly why HIV is so hard to get rid of; by the time it manifests itself as AIDS, countless cells already contain its DNA signature.) Biologists even speculate that 5%-8% of modern human DNA is actually retrovirus injections. But in any case, there have been successful trials for using retroviruses in beneficial ways.
205** The new technology CRISPR even enables hacking, by cutting parts of DNA that are unwanted, then replacing it with another one through a vector, perhaps a retrovirus. The best (or freakiest part depending on your mileage)? CRISPR kits are dirt cheap, and biohacking can be done in a school lab or even a garage.
