Weizmann Institute of Science researchers have developed DNA molecular computers using enzymes, with ATP as fuel.

“Our experiments demonstrate for the first time that we may use a DNA molecule as an input for computation, and at the same time fuel this computation by the energy stored in the very same molecule,” according to researcher Ehud Shapiro. “Such combination, although theoretically conceivable, is practically impossible with conventional electronic computers.”

The experiments demonstrate 3 x 1012 automata per microliter performing 6.6 x 1010 transitions per second per microliter.
