Abstract:

This report reviews the research in chemical sensing at the nanometer scale using amperometric detection focusing on publications from January 2004 to September 2005. The devices discussed fall into two categories chemresistors and chemFETs. In either configuration, the number of carriers available in the channel, and hence the devices transconductance, changes as a function of analyte exposure. Devices based on inorganic nanowires specifically limited to metal oxides and silicon, conductive organic polymer fibers, and carbon nanotubes are discussed as issues of sensitivity, selectivity, responserefresh times, etc.
