Imperial College London researchers say they have developed a method for building logic gates out of bacteria and DNA, which makes them the most advanced biological logic gates ever created.

"Now that we have demonstrated that we can replicate these parts using bacteria and DNA, we hope that our work could lead to a new generation of biological processors, whose applications in information processing could be as important as their electronic equivalents," says Imperial College London professor Richard Kitney.

The researchers say that biological logic gates could eventually form the building blocks for microscopic biological computers. The key advantage to the new biological logic gates is that they behave like electronic logic gates. The biological logic gates also are modular, which enables them to be fitted together to make different types of logic gates.

The researchers now will attempt to develop more complex circuitry consisting of multiple logic gates.
