Nanopunk refers to an emerging subgenre of science fiction that is 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 and bio-nanotechnologies are widely in use and nanotechnologies are the predominant technological forces in society. The genre is mainly concerned with the artistic, psychological, and societal impact of nanotechnology, rather than aspects of the technology which itself is still in its infancy. Unlike 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 as a more optimistic outlook that might emphasize potential uses of nanotechnology.
