Chem Commun (Camb). 2011 Jun 7;47(21):6048-50. doi: 10.1039/c1cc11517k. Epub 2011 Apr 28.

Abstract

An innovative sensor for the detection of nerve agents in the gas phase based on a carbon nanotube field-effect transistor was developed. A high sensitivity to organophosphorus gases was obtained by modifying gold electrodes with specific tailor-made self-assembled monolayers.
