{{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.

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.

== Anime
* 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]].
Line 58 ⟶ 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 79 ⟶ 80:
== [[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 92 ⟶ 94:
* 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.
