Tools design DNA-nanotube logic

Researchers have recently begun to use DNA to assemble carbon nanotubes into transistors, the building blocks of computer chips.

Researchers from Duke University are aiming to make the process easier with a suite of computer-aided design (CAD) tools designed to build computer circuits at a density of 2,500 transistors per square micron — about 30 times more closely packed than devices made using current chipmaking technologies.
