DNA Origami for Faster, Smaller Computer Chips

Using DNA structures, researchers may be able to construct tinier, cheaper chips

  • August 17, 2009

Artificial, self-assembling DNA structures may help make smaller and cheaper microchips, according to research presented in the latest issue of Nature Nanotechnology. Tinier microchips would allow faster computers and other electronics.

Researchers from IBM and the California Institute of Technology used a technique known as DNA origami, where a long strand of DNA is folded into a shape with many shorter strands dubbed staples, creating a three-dimensional shape. In the paper, the researchers demonstrated using DNA origami-shapes as a scaffold for carbon nanotubes–a trick that could eventually be used to create nanoscale microchips.

The DNA structures are tiny enough to have features measuring six nanometers–the current industry standard for microchips is 45 nanometers. The process could replace the expensive tools manufacturers currently use to make tiny chips, although IBM suggests that it could take up to 10 years to test and refine the process for manufacturing.
