Patent ID: 7964143

Claim:
A nanotube-based sensor, comprising: a first insulating layer over a first conductive layer formed on a substrate, the first insulating layer: (i) having a first aperture formed therein exposing a region of the first conductive layer, with a deposited nanotube having a first end in contact with the exposed region of the first conductive layer, and (ii) configured to generate an electric field around the first aperture; and a second end of the deposited nanotube coupled to a molecule having a functional group for interacting with a sample; wherein the first aperture is sized to allow a plurality of nanotubes to contact the exposed region of the first conductive layer; and wherein after the nanotube is deposited, the deposited nanotube is adapted to re-configure the electric field to thereby prevent other nanotubes from being deposited on the exposed region of the first conductive layer.
