Nanopunk refers to an emerging genre of speculative science fiction (sci-fi) still very much in its infancy in comparison to other genres like that of cyberpunk or steampunk.

The genre is similar to biopunk, but describes the world where the use of biotechnologies are limited or prohibited, so only nanites and nanotechnologies are widely use (while in biopunk, bio- and nanotechnologies often coexist).

Currently the genre is more concerned with the artistic and physiological impact of nanotechnology, than of aspects of the technology itself which is still in its infancy. Unlike the cyberpunk protagonist, a low-life yet technologically advanced character, the personification of a nanopunk can be set 'hard' or 'soft', depending on your views of the impact nanotechnology will have on our future.
