Abstract
A chemical sensor, methods of forming the same, and methods of performing chemical detection include a carbon nanotube test surface. A detector is configured to receive a signal from the carbon nanotube test surface responsive to illumination on the nanotube test surface. A matching module is configured to determine whether a chemical is present at the carbon nanotube test surface based on a comparison between the signal and a spectral profile of the chemical.

A chemical sensor, comprising:
- a carbon nanotube test surface;
- a detector configured to receive a signal from the carbon nanotube test surface responsive to illumination on the nanotube test surface;
- and
- a matching module configured to determine whether a chemical is present at the carbon nanotube test surface based on a comparison between the signal and a spectral profile of the chemical that is based on an overlap between plasmon modes and vibrational modes of the chemical and the detector.
