Molecular nanotechnology was popularized and proved by the monograph: Engines of Creation, by Eric K. Drexler.^[1] Molecular computers involve the storage and processing of data at the molecular level.

Biological computing[edit]

The obvious existence proof provided by Drexler was the processing and storage of data by DNA and other biomolecules in living systems. DNA code data using 4 molecular letters, A, C, G and T. This makes DNA a base 4 storage device. It has error control hardware, and the abillity to make copies of itself. Viruses are able to edit DNA to their own ends.

Non biological devices[edit]

Nanotubes made of tubular graphite sheets have been used as conductors and as transistors in experimental molecule sized computational devices.
