Editing Molecular nanotechnology (section)

==Works of fiction==
* In ''[[The Diamond Age]]'' by [[Neal Stephenson]], diamond can be built directly out of carbon atoms. All sorts of devices from dust-size detection devices to giant diamond zeppelins are constructed atom by atom using only carbon, oxygen, nitrogen and chlorine atoms.
* In the novel ''Tomorrow'' by Andrew Saltzman ({{ISBN|1-4243-1027-X}}), a scientist uses [[nanorobotics]] to create a liquid that when inserted into the [[bloodstream]], renders one nearly [[wikt:invincible|invincible]] given that the microscopic machines repair tissue almost instantaneously after it is damaged.
* In the [[roleplaying game]] ''[[Splicers]]'' by [[Palladium Books]], humanity has succumbed to a "nanobot plague" that causes any object made of a non-[[precious metal]] to twist and change shape (sometimes into a type of [[robot]]) moments after being touched by a human. The object will then proceed to attack the human. This has forced humanity to develop "biotechnological" devices to replace those previously made of metal.
* On the television show ''[[Mystery Science Theater 3000]]'', the [[Nanites]] (voiced variously by [[Kevin Murphy (actor)|Kevin Murphy]], [[Paul Chaplin (actor)|Paul Chaplin]], [[Mary Jo Pehl]], and [[Bridget Jones (actor)|Bridget Jones]]) – are self-replicating, bio-engineered organisms that work on the ship, they are microscopic creatures that reside in the Satellite of Love's computer systems. (They are similar to the creatures in ''[[Star Trek: The Next Generation]]'' episode "[[Evolution (TNG episode)|Evolution]]", which featured "nanites" taking over the ''Enterprise''.) The Nanites made their first appearance in season 8. Based on the concept of [[nanotechnology]], their comical ''[[deus ex machina]]'' activities included such diverse tasks as instant repair and construction, hairstyling, performing a Nanite variation of a [[flea circus]], conducting a microscopic war, and even destroying the Observers' planet after a dangerously vague request from Mike to "take care of [a] little problem". They also ran a [[microbrewery]].
* ''[[Stargate Atlantis]]'' has an enemy made of self-assembling nanorobots, which also convert a planet into grey goo.
* In the novel "Prey" by Michael Crichton, self replicating nanobots create autonomous nano-swarms with predatory behaviors. The protagonist must stop the swarm before it evolves into a grey goo plague.
* In the films ''[[Avengers: Infinity War]]'' and ''[[Avengers: Endgame]]'', [[Tony Stark (Marvel Cinematic Universe)|Tony Stark]]'s [[Iron Man's armor (Marvel Cinematic Universe)|Iron Man suit]] was constructed using nanotechnology.
