US Patent 7928432 - CNT molecular sensor

http://www.freepatentsonline.com/7928432.html

This patent is from researchers at Columbia University and teaches a variation of molecular sensor formed from a single walled carbon nanotube. Claim 1 reads:

1. A method of fabricating a molecular electronic device, comprising:

(a) disposing a SWNT on a base layer;

(b) disposing two or more electrodes on the SWNT;

(c) using a lithographic process to locally cut the SWNT between the electrodes to form a gap therein; and

(d) disposing a molecular wire across the gap so that each end of the molecular wire contacts an electrode.
