DNA computing is a form of computing which uses DNA and molecular biology, instead of the traditional computer technologies. This field was initially developed, in 1994, by Leonard Adleman (University of Southern California). In addition, Bernhard Yurke (Bell Labs) has developed DNA motors.

Since first Adleman experiments many advances has been made, and various Turing machines has been proof to be constructable.

They are works over one dimensional lengths, bidimensional tiles, and even three dimensional DNA graphs processing.

At 2003-2004 there is no known application for DNA computing that is able to his incredible parallelism capabilities. The input/output interfaces still slow and expensive.

The DNA computing technology is related to the micro mechanical technology (that also use DNA for structural and mechanical constructions) (switches, gates, etc...).
