Abstract

An electronic system (800') for detecting analytes (801), such as carbon dioxide, is provided, using a nanostructure (106) sensor (CO2 sensor 802) The CO2 sensor (802) may comprise a substrate (104) and a nanostructure (106), such as a one or more carbon nanotubes disposed over the substrate (104) (e g, as a network) One or more conductive elements (110, 112) may electrically communicate with the nanostructure (106). A counter or gate electrode may be positioned adjacent the nanostructure (106). A functional ization material (120) reactive with carbon dioxide may be included, either disposed in contact with the nanostructure (106) or isolated by a dielectric The sensor may be connected to a circuit (122) responsive to changes in CO2 concentration in the environment.
