'DNA circuits'

(Article Precis, 14/Nov/1998, Issue 2160, p7)
It may soon be possible to use DNA to connect together miniature circuit devices, if a patent pending by the San Diego based Nanotronics and the University of California is approved.

Different DNA substances which are known to bond together are applied to a substrate's surface, and to the target component. Placed in a soluable medium and brought together, the DNA coatings chemically bond, securing the element to the substrate.

The technique can be used to coat large areas of a 2D or 3D surface with a great number of nano-scale elements, eg. photodetectors in a telescope sensor.
