Scientists have increasingly been linking biological material like DNA to electronics and nanotechnology to create powerful hybrids. For example researchers at McGill University had found a quasi-three-dimensional electron crystal that could enable them to harness quantum physics to make increasingly small computer chips and MIT has developed sensors made out of carbon nanotubes that were wrapped in DNA. At IBM scientists are using DNA to find a new way to build processors by linking DNA and nanotechnology. IBM is looking for the DNA to act as scaffolds, or miniature circuit boards, for the highly precise assembly of chip components, like nanotubes, nanowires and nanoparticles. Using this technique, manufacturers should be able to build "significantly smaller" chips (from 45 down to 22 nm size) than has been possible with current semiconductor fabrication technology according to IBM.
