US Patent 7786540 - Vertical nanotube fabric sensor

This latest patent from Nantero teaches a nanotube-based chemical sensor which may be easier to fabricate and integrate with CMOS electronics than earlier versions. Claim 1 reads:

1. A sensor platform, comprising

a sensor element comprising a non-woven nanotube fabric and having an electrical characterization;

a support structure, comprising a substrate, for supporting the sensor element so that it may be exposed to a fluid, and having a major surface of the substrate substantially non-parallel to the sensor element; and

control circuitry to electrically sense the electrical characterization of the sensor element so that the presence of a corresponding analyte may be detected.
