Biological computing is the advanced science of using biological products to perform actions that would traditionally be done using components like copper wire and fiber glass. Common biological components being used in these studies include amino acids and DNA. Computational functions can be performed by manipulating natural chemical reactions found in these substances. Currently, biological computing is very limited in its capabilities and can only perform simple logic calculations.
A team at MIT is researching and working on biological computing capabilities, focusing on cellular computing machines as a starting point.
