Nanopunk

Nanopunk refers to an emerging subgenre of science fiction still very much in its infancy in comparison to its ancestor-genre cyberpunk and some of its other derivatives.

The genre is especially similar to biopunk, but describes a world where nanites are widely in use and nanotechnologies the predominant technological forces in society.

Currently the genre is mainly concerned with the artistic, psychological and especially societal impact of nanotechnology, rather than aspects of the technology which itself is still in its infancy. Unlike the cyberpunk which can be distinguished by a gritty and low-life yet technologically advanced character, nanopunk can have a darker dystopian character that might examine potential risks by nanotechnology as well a more optimistic outlook that might emphasize potential uses of nanotechnology.
