IBM Scientists Build Computer Chips From DNA

Scientists at IBM are experimenting with using DNA molecules as a way to create tiny circuits that could form the basis of smaller, more powerful computer chips.

The company is researching ways in which DNA can arrange itself into patterns on the surface of a chip, and then act as a kind of scaffolding on to which millions of tiny carbon nanotubes and nanoparticles are deposited. That network of nanotubes and nanoparticles could act as the wires and transistors on future computer chips, the IBM scientists said.
