Biocomputers are devices that deal with storing, retrieving and processing data. They operate with systems of biologically derived molecules, like proteins and DNA. The biocomputers’ development was made possible with the expansion of the new science called nanobiotechnology. This field includes all technologies which that utilize materials with dimensions that range from 1-100 nanometers, and biologically-based materials as well.
Another definition of nanobiotechnology states that the technology deals with the design and engineering of proteins that can later be used in more substantial structures. Nanobiotechnology enables scientists to engineer and restructure bio-molecular systems in such a way that that they will interact and result in the computational functionality of a computer.
