{{quote|''"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."''
|'''Col. Corazon Santiago - "Planet: A Survivalist's Guide"''', ''[[Sid Meier's Alpha Centauri]]''}}
In Latin, ''nanus'' means "dwarf". In science, the prefix ''nano-'' means "one billionth" of something. Nanotechnology is technology on a scale of 1-100 nanometers (1 nanometer being one billionth of a meter.)
For a long scale of sizes see e.g. [http://www.falstad.com/scale/ here]. But of what's relevant to nanoscale construction - a hydrogen atom is about <ref>on this scale things don't ''look'' blurry, they ''actually are'' quite blurry</ref> 0.1 nanometers across, ribosomes <ref>the part of a cell that builds proteins to received arbitrary data</ref> are around 20 (prokaryotic) to almost 30 (eukaryotic) nm long; [https://web.archive.org/web/20160809135552/http://classes.midlandstech.edu/carterp/courses/bio225/chap04/lecture2.htm bacteria] are in range of 200-2000 nm; visible light has a wavelength of 400-800 nm, a human cell nucleus is about 1700 <ref>it holds [https://web.archive.org/web/20160216134617/http://bitesizebio.com/8378/how-much-information-is-stored-in-the-human-genome/ about 1.5 Gb]] worth of raw data - but note that it's ''the whole'' storage unit (though there's also another vital, but self-contained unit - in mitochondria), and in a form optimized for several uses and, shall we say, viable level of resilience, not for sheer density</ref>, and a human hair is about 100,000 nm wide. Which gives a good idea of limitations and complexity involved - and raises a question of at which point you have a nanorobot if you start with "cyborgizing" some bacteria.
Nanotechnology has become an all-purpose [[A Wizard Did It|magic]] substitute for soft science fiction and sci-fi-flavored fantasy. Nano is the latest [[Sci Fi Name Buzzwords]]; it is the new pseudo-Greek for [[Phlebotinum Du Jour|phlebotinum]]. Nanotech supplies a myriad of exciting powers with a satisfying patina of plausibility.
In an apparent contradiction, nanotechnology leads to interesting plots and settings in [[Mohs Scale of Science Fiction Hardness|hard science fiction.]] If one could make a tiny robot
Once 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.
Line 16 ⟶ 19:
Note that real-life physics puts constraints on what nanomachines could accomplish; for instance, without some source of energy, they will just sit there being molecules, or at best work veeeery slowly using ambient energy. But most writers [[Did Not Do the Research|rarely study the subject in any detail]]; it's easier to just use them as [[Green Rocks]] that can do anything the plot requires.
One 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 "[[Grey Goo]]" scenario. Some scientists (and noted homeopathy fan, HRH The Prince of Wales) have expressed concern that this scenario could actually happen in real life, although most consider it extremely [https://web.archive.org/web/20131025044513/http://nanotechweb.org/cws/article/indepth/19648 unlikely].
Because it is so powerful, in settings where science is ''inherently'' bad expect nanotech to be right up there on the [[Scale of Scientific Sins]].
Line 23 ⟶ 26:
Nanites themselves will usually either be [[Sliding Scale of Robot Intelligence|dumb as bricks]], or [[Hive Mind|networked into a fully sentient mass]]. Some works may invoke [[Mechanical Evolution]] to make the nanomachines smarter/better/deadlier.
{{examples}}
▲== Anime & Manga ==
* The Otome from ''[[Mai-Otome]]'' receive their powers via nanomachine injections; they self-destruct when the female body's [[Virgin Power|exposed to semen.]]
* The series ''[[Kiddy Grade]]'' bases a lot of technology on "Nano-mist"—a fog made up of trillions of nano-scale machines, which can achieve amazing effects—from keeping a 64 thousand kilometer long starship from collapsing under its own mass, to creating a barrier, to repairing damage, to [[terraform]]ing a planet. Also known as [[wikipedia:Utility fog|utility fog]].
** ''[[Kiddy Grade]]'' kicks [[Willing Suspension of Disbelief]] in the teeth throughout the series, and explains ''everything'' by [[Hand Wave|handwaving]] some nonsense about nanomachines. While changing clothes in seconds or maybe even the "make a whip out of lipstick" trick are somewhat old hat, one pair of characters ''[[You Fail Physics Forever|has the nanomachine-induced physics-warping superpower]] [[Gravity Sucks|of manipulating black holes with their bare hands]]''.▼
** It was however suggested in-story (and confirmed in the sequel) that this is malarkey even inside the story; the ES members' abilities are not nanomachine-powered, but in fact seem to be actual (possibly Clarkian) magic.▼

* In ''[[Martian Successor Nadesico]]'' exposure to terraforming nanomachines had an interesting effect on humans born on Mars. "Image Feedback System" Nanomachines were also used to interface with various machinery. On Mars, IFS nanomachines were required for pretty much any heavy equipment, but on Earth they served only as the [[Unusual User Interface]] for [[Humongous Mecha]] and other military vehicles. This led to Martian civilian Akito getting a lot of flak from [[The So-Called Coward|Earth-natives who assumed he was a military deserter]], and eventually getting [[The Call Knows Where You Live|press-ganged]] into piloting.
* ''[[Getter Robo]]'' [[Hand Wave|hand waves]] its [[Transforming Mecha]] in the Armageddon OVA by attributing the transformations to nanomachines.
* ''[[Turn A Gundam
** And they allow teleportation, regeneration and more.
* ''[[Mobile Suit Gundam 00|Gundam 00]]'' uses nanomachines to explain why the crew of Ptolemaios can stay in space for extended periods of time and not suffer bone density loss and so on. They are also the explanation, together with genetic modification, on why Innovades like Tieria do not age.
Line 46 ⟶ 47:
* In ''[[Ghost in the Shell: Stand Alone Complex]]'', nanomachines are widely used. In the first season, one of the potential treatments for cyberbrain sclerosis is based on nanomachines (although it isn't very effective). One episode also mentions that nanomachines are used to counteract air pollution. ''2nd GIG'' introduces the "Japanese Miracle"; a nanomachine-based technology for neutralising radioactive fallout from nuclear explosions.
** Though, being written before "nano" became a popular buzzword they're called ''micro'' -machines.
*** If it collects substances that inevitably and spontaneously explode into fragments far too energetic to contain on its scale, it ''needs'' massive redundancy.
* Viluy from ''[[Sailor Moon]]'' attacks with nanomachines. {{spoiler|After one of Sailor Moon's attacks causes them to malfunction, they turn on their creator.}}
* Yami from ''[[To
** As expected of an Eve-expy.
** And now Yami has a 'younger sister', Mea Kurosaki with the same powers, presumably from the same source.
Line 57 ⟶ 59:
==
* ''[[The Authority]]'' - Authority member The Engineer replaced all of her blood with nanomachines. She can [[Green Lantern Ring|create nearly anything with these]], from [[Arm Cannon]]s to [[Me's a Crowd|duplicates of herself]]. This being ''[[The Authority]]'', many of the implications of these powers are investigated.
* During Grant Morrison's ''[[X-Men (Comic Book)|X-Men]]'' run, Cassandra Nova attacked the team on a cellular level with nanosentinels.
Line 77 ⟶ 79:
* The magic behind virtual reality in ''[[Kimmie 66]]''.
== [[Fan Works]] ==
* The last gasp of the remaining members of the American bloc of the Collective in ''[[The Secret Return of Alex Mack]]'' is an attempt at a nanobot-based plague which goes [[Grey Goo|"worst case"]].
* In the ''[[Harry Potter]]'' fic ''[[The Arithmancer]]'', Hermione Granger creates a magical nanite weapon that she calls [[Narnia|"The Deplorable Word"]], and which she uses to defeat Bellatrix Lestrange at the climax of the story.
* Used in the [[Phlebotinum Du Jour]] and [[Magic From Technology]] senses of the trope in the [[Mega Crossover]] ''[[My Apartment Manager is not an Isekai Character]]'', and usually supplied by [[Sufficiently Advanced Alien|Washuu-chan]]. Nanotech has been used to give multiple characters [[Heal Thyself|ridiculously fast medical treatment with a side-order of life extension]].
== Films ==
Line 85 ⟶ 92:
* When used as directed, the nanobots on the salvage ship in ''[[Friday the 13th (film)]]'' can heal wounds and restore tissue damaged by cryogenic freezing. They can also be used to rebuild a shot-to-living-hell psycho killer into a [[Nigh Invulnerable]] cyborg. ...Yay?
* Nanomachines are used in the ''[[I, Robot (film)|I Robot]]'' movie to "execute" problem robots.
* In the remake of ''[[The Day the Earth Stood Still (1951 film)|The Day the Earth Stood Still]]'' nano-insects ([[Grey Goo|grey-goo]] style) {{spoiler|[[Kill All Humans]]}}.
* ''[[Star Trek: First Contact]]'' was the first time the Borg were shown using nanotech as an assimilation tool (see below under Live Action TV).
* The [[MacGuffin]] in ''[[Ballistic
* ''[[Transformers Film Series]]'' - According to [[All There in the Manual|The Official Movie Guide]], Protoforms are made up of densely packed nanomachines. This is the semi-official [[Hand Wave]] for any transformation "cheats" in the films and where, for example, the rubber for Optimus' tires comes from.
* ''[[G.I. Joe: The Rise of Cobra]]'' features the nanites, originally created for medical intents and later weaponized (sometimes ''with medical intents'', for creating [[Super Soldier]] [[Elite Mooks]] who had a minor [[Healing Factor]] and [[Brainwashed and Crazy|parts of their brains destroyed to become fearless]]). And seems like [http://gijoe.wikia.com/wiki/Nanomites they already existed] in a [[G.I. Joe]] comic.
Line 102 ⟶ 109:
* In the second of the ''[[Thursday Next]]'' series of novels by Jasper Fforde, Thursday's inventing uncle Mycroft invents some nanomachines. Her time-traveling [[Time Police|Chronoguard]] rogue father who does not exist in real time (that's a mouthful) eventually {{spoiler|has to time travel to the beginning of life on Earth with the nanomachine colony (instructed to convert all organic material into Dream Topping) in his fist, to prevent the world ending in a sugary, confectionery manner. Turns out we are all evolved from Dream Topping. Which actually explains a lot}}.
* The epilogue of ''Look To Windward'' by [[Iain M Banks]] features an artificial shape-shifting assassin composed of "E-Dust" (Everything-Dust), originally intended as a building material but inevitably turned to darker purposes. ''[[The Culture]]'' in general seem to have progressed beyond nanotech, referring to 'picofoam' as the building blocks of their AI Minds.
** "Picofoam complex" is the ''backup'' computational substrate for a mere ship drone's AI core, as described in ''[[The Culture/Excession|Excession]]''. Most of [[Deus Est Machina|a true Culture Mind]] actually exists in hyperspace, where it may function unburdened by pesky nuisances like the speed of light and neutron decay.▼

* The anti-Descolada virus designed by the heroes in the ''[[Ender's Game]]'' sequels. Ironically, {{spoiler|the original Descolada virus counts too, as it was engineered by an unknown alien race as a terraforming agent}}.
* The plot of the ''Moonrise'' and ''Moonwar'' by Ben Bova revolve around nanomachines. A subversion occurs when one character proposes making nanomachines that act like dust, to blind the invading army, and another character suggests just using dust instead.
Line 175 ⟶ 181:
* ''[[Metal Gear Solid]]'' and its sequels use nanomachines for ''everything'', from transmissions to healing bleeding wounds to {{spoiler|aiding in a fake possession}}.
** [[Parrot Exposition|Nanomachines?]]
** In ''[[Metal Gear Solid 2: Sons of Liberty|Metal Gear Solid 2]]'', Raiden actually has all of his ''blood'' replaced with ''synthetic blood teaming with nanites''. Never mind the actual viability of that particular gruesome mashup, this is what allows him to interact wirelessly with nerds. Uh, nodes. This is actually perfectly viable, or at least it should be in the next few decades. [https://web.archive.org/web/20100420041524/http://www.kurzweilai.net/meme/frame.html?main=
* Vanilla H's healing ability in the ''[[Galaxy Angel (video game)|Galaxy Angel]]'' games comes from nanomachines. This works on both ships (her Angel Wing, Harvester, is a living nanomachine colony) and people (with her pet, a catlike living [[Lost Technology]]). Vanilla is one of the very few people that can pull this off, and became an [[Emotionless Girl]] as a side effect of honing her skills. Nano-Nano Pudding, from the later games, is another living [[Lost Technology]], this time a [[Catgirl]]. Like Vanilla's pet, she too is constructed from nanomachines.
* In the ''[[Galaxy Angel (anime)|Galaxy Angel]]'' anime, none of this is mentioned at all, and Vanilla's powers may or may not come from a magical bead.
* While ''[[Warcraft|Warcraft III]]'' doesn't actually use them in the story, a custom map called S.W.A.T. Aftermath calls the [[Mana]] resource 'energy' instead and the creator refers to the 'Nanites' in it as being able to do pretty much anything. A fan comic parodies it by having the creator call the Nanites concept 'magic', which is ill-received by the scientific community. After renaming it Nanites, he's considered a genius. As a note, the map's creator has said [[A Wizard Did It|"Nanites did it"]] when some of the community begin to over analyze how certain technologies work.
* ''[[Total Annihilation]]'' used nanobots (via "Nanolathes") for construction. One of the creators explained it thus: "It would have been too complex and time consuming to have little guys with hammers and scaffolds every time something was built in the game. It also wasn't futuristic enough. We needed something like magic, but with a thin veneer of science around it. Nanotechnology to the rescue!"
** Ironically, this has turned out to be a fairly reasonable use of nanotech. Now imagine a game of total annihilation that drags out for months, and apply to the real world. ''[[Total Annihilation]]'s'' [[Spiritual Successor]], ''[[Supreme Commander]]'', uses Nanolathes as well, but calls them "Protocrafters" and gives each faction's unique graphics.▼

** ''Total Annihilation'' used nano''technology'' but not nano''machines''. The two are very different! ''Nanolathing'' is the process by which solid objects are created by fabrication systems, eg Commanders, Factories and Engineers. Things must be actively constructed by a fabricator; they cannot self-assemble. Once built, non-fabricating units and buildings cannot replicate or regenerate: they're just perfectly normal (albeit very high-tech) machines. A select few buildings can upgrade, but most buildings and units cannot and no unit can change itself dramatically. A nanolathe could be visualised as a very fast, very powerful, multi-material 3d-printer with molecular-scale resolution.
*** It takes over enemy robots, however.
* The plotline of the video game ''[[Hostile Waters]]: Antaeus Rising'', by [[Warren Ellis]], is based on nanotechnology. In the year 2012, nanotech "Creation Engines" were developed and released to the world at large. Able to dispense anything a person could want, at any time - on demand - they cause [[The Singularity|"the world to go sane"]]; Revolution happened, [[Obstructive Bureaucrat|power cliques]] were overthrown and the world becomes a [[Utopia]]. The game takes place is the fictional year 2032, where {{spoiler|the old power elites have perverted nanotechnology for their own uses, creating weapons of war with which to blackmail the rest of the world into servitude again. Or so it seems, at first...}}
* ''[[Deus Ex]]'' - Nanites are central to gameplay and a strong part of the plot. The protagonist, JC Denton, has nano-augmentations, such augmented vision. During the game, fresh infusions of nanites add entirely new abilities and upgrades for existing abilities. All his augmentations were powered by his body's own bioelectrical energy—a high tech equivalent of mana. The abilities themselves were fairly believable, though if you built your character right you were essentially an [[Invisible]], [[Super Speed|super-fast]], [[Super Strength|super-strong]], [[Healing Factor|rapid-healing]] dude wielding a [[Power Glows|sword that could kill robots in a single hit]]. Of course, you would completely drain your bioelectrical energy in about twenty or thirty seconds of pure awesomeness, but hey, what price glory?
** The sequel, ''[[Deus Ex:
* ''[[Sid Meier's Alpha Centauri]]''. All over the place at higher levels. Several technologies have to do with the stuff (Nanominiaturization, Nanometallurgy, and Industrial Nanorobotics being the coolest-named), most of which give you some pretty cool stuff (and allow you to build carriers and submarines for the first time for some reason).
** On one hand, upon researching Industrial Nanorobotics, you hear an excerpt from one of Miriam's screeds against new technology:▼
{{quote|Already we have turned all of our critical industries, all of our material resources, over to these...things...these lumps of silver and paste we call nanorobots. And [[

** On the other hand, [http://www.youtube.com/watch?v=aKcEwUcVBHs Santiago's opinion on the subject]. On another note, the video and accompanying voiceover [[Shown Their Work|indicate that, as usual, the developers did the research]]: the bots are networked, seem to draw power from their canisters, and have to get their raw material from somewhere (the video shows them devouring a battlefield, including a [[Nightmare Fuel|dead body's hand]], to make one hovertank).
* ''[[Ratchet and Clank]]'' uses Nanotech to explain the existence of hitpoints. After a set point in the first game, the Nanotech can be upgraded to increase the health of Ratchet.
Line 199 ⟶ 204:
* The Necris from the ''[[Unreal]]'' series are humans who had all their blood replaced with Nanoblack, a "black goo" of nanomachines. The Necris are technically [[The Undead|undead]] (as the name implies), since Nanoblack is harmful to living organisms and the blood transfusion only works on dead people.
* ''[[Iji]]'' uses nanotechnology for everything. All the enemy soldiers and Iji herself use nano to enhance their movement and protect their bodies. Also, their "nanoguns" can shapeshift their internal components to act as any kind of weapon and assemble projectiles inside the barrel.
* The entire ''[[Wild
* The GenSelect Device, from ''[[Wing Commander (video game)|Wing Commander IV]]'', was weaponized Nanomachines designed to eliminate anyone with "inferior" genes.
* All of the ''[[Red Faction]]'' games feature nanotechnology, primarily as plot points. Used quite realistically in the first and third games; not so much in the second.
Line 208 ⟶ 213:
* [[Anarchy Online]] takes this trope to heart and runs with it, using nanobots for frickin' ''everything.'' "Magic" is essentially just free-floating nanobots in the air being told to do something, your [[Mana]] is [[Call a Rabbit a Smeerp|called Nano Points]], and these 'bots make everything from guns, to [[Humongous Mecha]], to that [[Arson, Murder, and Jaywalking|super-potent beer]] that all ''nano-augmented'' species that live on Rubi-Ka can't get drunk from ([[Monkey Island 2: LeChuck's Revenge|"It's just as nasty-tasting and foul smelling as the real thing, but without the alcohol."]]). Hell, these things can even change the way things taste. You name it, nanobots are probably behind it on Rubi-Ka. Except for resurrection; you need the local [[Green Rocks]] for that.
* A little-known RTS game from the DOS era called ''War, Inc.'' puts you in charge of a [[Private Military Contractor]]. The vehicles are manufactured by nanobots from raw materials that you must harvest in-mission (and your infantry is made by incredibly high-speed cloning).
* One of the main resources in the RTS ''[[Achron]]'' is called Liquid Crystals (LC for short) and is made of a mix of common atoms and nanobots in a liquid-crystal framework. When you order a unit to construct a building the unit drops a tiny transponder seed which signals local teleportation infrastructure to teleport the right quantity of LC to that location. The nanobots in the LC then assemble the building using the atoms contained within it. When you build a unit the LC is teleported into the factory where it assembles into the units gear in a similar way (and the pilot is supplied separately).

* At least two types of nanomachines showed up during the [[Crossover Wars]], mini-gnomes from ''[[Magical Misfits]]'' were sent to the Evil Overlords headquarter to sabotage things and nanite versions of ''[[Mind Mistress]]'' were left there to monitor things.
* In ''[[Schlock Mercenary]]'' nanomachines are almost omnipresent, and several Story Arcs have featured them heavily. Note that they generally are of very specific limited use and/or act as a part of large and complex systems. The types that can survive in the open at all still have heat capacity and resistance to radiation reasonable for their size - hardened ones are vacuum-capable but all are killed if anyone fires in their general direction anything from a powerful searchlight and up. Or if they run into "antiseptic", like [http://www.schlockmercenary.com/2007-09-11 anti-nannotic film].
** "Nanny-cams", bugs that are dispensed from a squirt-gun. While devices on the scale of light wavelength obviously can't use ray optics, it's the right size for antenna arrays.
** Medical. Regeneration vats are awesome, but they include external control and support systems, and expensive. The only common piece of multi-species medical equipment in the field is a body-bag that keeps the brain alive in anabiosis.
** "Blood-nannies" - self-sustaining swarms of medical nanobots controlled by implanted microcomputers, sometimes interfaced to the user's brain, as explained [http://www.schlockmercenary.com/2011-03-08 here]... of course, implanting stuff in the brain is made safer by using yet another nanobot system to do all the cable-work.

[http://www.schlockmercenary.com/2004-12-03 Really expensive] to install and restricted in many polities. High-end ones may include "weapon package", so when an operative is disarmed, there still are surprises, since micro-implants, let alone swarms of nanobots spread through the body, are either overlooked as fairly common or left alone because it's hard to remove or disable them without killing the host (short of throwing the latter in a jar swarming with your own for a while).
** Weaponized nanites - not much good for an open battle ([http://www.schlockmercenary.com/2012-11-14 vulnerable] to heat and ionizing radiation, and as such [[Kill It with Fire|purged with fire]] in small areas and [http://www.schlockmercenary.com/2012-06-08 swept with beams] in large), but a very nasty assassination weapon. They are targeted (for example, [http://www.schlockmercenary.com/2012-07-29 eating their way along nerves to the victim's brain, then make it non-recoverable]) and self-destruct later. Variants [[Typhoid Mary|keeping a live carrier intact]] may be voluntarily controlled by the carrier or even nanobots may have limited control over one's body - for designs carried in humans, the all-time favorite delivery method is [[Vomit Indiscretion Shot|projectile vomiting]] a [http://www.schlockmercenary.com/2012-11-13 full stomach of] stuff lethal in mist-droplet quantities.
** The "cloud AI" types stand out, but from what we have seen, given enough of time and challenges those are prone to [[Zeroth Law Rebellion|evolving out of their initial rules]] one way or another even more than conventional fixed-hardware AI.
** Also, one big and already metal-rich ecosystem seems to have co-evolved (over millions of years) into symbiosis with what is implied to be runaway nanobots, formerly used by the cyborgized sophonts who owned the place, and now electroplate bones and carapaces of local fauna (and at least one of these species also have developed sapience over this time).

Gets pretty heavy with it, too, as the show loved to sneak in more complexity than most Saturday morning cartoons get away with; the nanomachines here run on a [[Applied Phlebotinum|unique form of power]] known as "Trans-Phasik Energy" or "T-Juice"—the flipside being that said energy is [[Plot-Driven Breakdown|burned rather quickly in combat]]. The nanites have symbiotic relationship with the protagonist: if they go offline, he dies. Surprisingly not played for a plot point as often as one might think so much as an occasional inconvenience... until the show's ''entire third season'', where {{spoiler|the government forces the agency to disband after terrorists steal the generator and nearly wipe out the UN with it. It is implied that the main character is living on borrowed time without the full-size power generator, and that he will die in the near future with only the portable model to fall back on. Whenever he powers up, he's burning off said time. [[Nice Job Breaking It, Hero|Nice Job Killing Yourself, Hero?]]}}
* In the ''[[Gargoyles]]'' episode "Walkabout", [[Heel Face Turn|villain turned good guy]] Dingo acquires a living suit made of nanomachines, after helping the Gargoyles convince said nanomachines not to eat Australia.
* [[Big Bad]] Slade on ''[[Teen Titans (animation)|Teen Titans]]'' blackmails Robin into becoming his apprentice by infecting the rest of the Titans with nanomachines that will kill them if he should decide to activate them.

** Nanomaterials: Super strong, very tough, and incredibly light, carbon nanomaterials. They are the [[Flying Brick]] of materials, in a sense. Variants include nanotubes, nanobuds, graphene sheets, etc.
** 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.
** 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 that also allows one to do crunches like it wasn't there. It's basically a man-made enhancement of the forces that allow [https://web.archive.org/web/20170814230258/http://www.teachertube.com/view_video.php?viewkey=720f7702c5ab116120e0&page=1&viewtype=&category= John Tickle to walk on custard].
* If you think about it, nanomachines are actually much [[Older Than They Think]], since proteins are essentially naturally occurring nanomachines. They are quite small, and they can accomplish functions like [[wikipedia:Enzyme|facilitating chemical reactions]], [[wikipedia:Na-K-ATPase pump|pumping substances across barriers]], and when working together can even [[wikipedia:Actomyosin|cause macro-scale movement]] of objects.<ref>Without nanomachines, you wouldn't have been able to
** 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.
** Another impressive example of an existing natural nanomachine is ATP synthase, which makes both the electric motor <ref>specifically, a proton-motive electrostatic motor, complete with armature and stator</ref> ''and'' the reciprocating engine.<ref>the ATP-producing end is basically a 3-cylinder radial engine</ref>

* This video, depicting [http://www.youtube.com/watch?v=PYxBy_Sz3Wc claytronics]. This is just a simulation, but it is running of 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.
* Middle Ages style stained glass contains gold nanoparticles. [[Clock Punk]] nanotech ahoy!
* One of TRIZ methods is trying to solve the problem with certain ideal machines. One of which, coincidentally, is a mass of "tiny people" who can do basic things like holding together or moving, know what they have to do and when. If you can do this, the next step is to move toward conventional sizes and methods until your machine actually can be built, of course.
