IBM experimenting with DNA to build chips - carbon nanotubes
Scientists at IBM are conducting research into arranging carbon nanotubes--strands of carbon atoms that can conduct electricity--into arrays with DNA molecules. Once the nanotube array is meticulously constructed, the laboratory-generated DNA molecules could be removed, leaving an orderly grid of nanotubes. The nanotube grid, conceivably, could function as a data storage device or perform calculations. OCZ Technology is also trying to use Carbon Nanotubes for an upcoming processor heat sink that we showed you here.
"These are DNA nanostructures that are self-assembled into discrete shapes. Our goal is to use these structures as bread boards on which to assemble carbon nanotubes, silicon nanowires, quantum dots," said Greg Wallraff, an IBM scientist and a lithography and materials expert working on the project. "What we are really making are tiny DNA circuit boards that will be used to assemble other components."
