Computers Made of DNA

Organic ‘Computers’ Made of DNA Could Process Data Inside Our Bodies (+Video)

The Conversation | September 3, 2015

We invariably imagine electronic devices to be made from silicon chips, with which computers store and process information as binary digits (zeros and ones) represented by tiny electrical charges. But it need not be this way: among the alternatives to silicon are organic mediums such as DNA.
DNA computing was first demonstrated in 1994 by Leonard Adleman who encoded and solved the travelling salesman problem, a maths problem to find the most efficient route for a salesman to take between hypothetical cities, entirely in DNA.

Some applications of synthetic biology in computing include the storage of digital information in organic material, cryptographic security via DNA-based encryption, and biological computation. Furthermore, development of a universal operating system for the biological cell, meaning to simplify the process of coding for organic systems or bio-computers is being attempted by the University of Nottingham’s AUdACiOuS project.
