US Patent 7368263 - Nucleic acid circuit element with conductive coatings

http://www.freepatentsonline.com/7368263.html

The use of nucleic acids for constructing circuit elements is of interest since it allows for self-assembly of the components and provides the possibility of 3D circuit architectures. This patent with fairly old priority (May 1998) seems fairly fundamental to a nucleic acid circuit element.

1. A circuit comprising:

at least one circuit element, the circuit element comprising at least one of a resistor, a diode, a capacitor, a transistor, and an inductor; wherein the at least one circuit element comprises a nucleic acid template with two or more sequential regions which are coated with different materials that are at least partially conductive.
