    • An electronic system and method for detecting analytes, such as carbon dioxide, is provided, using an improved nanostructure sensor (CO2 sensor). The CO2 sensor may comprise a substrate and a nanostructure, such as a one or more carbon nanotubes disposed over the substrate (e.g., as a network). One or more conductive elements may electrically communicate with the nanostructure. A counter or gate electrode may be positioned adjacent the nanostructure. A functionalization material reactive with carbon dioxide may be included, either disposed in contact with the nanostructure or isolated by a dielectric. The sensor may be connected to a circuit responsive to changes in CO2 concentration in the environment. Embodiments are described of medical sensing systems including one or more CO2 sensors. One embodiment comprises a breath sampling cannula which is connected to a sensor unit. In an alternative, the cannula permits supplemental oxygen to be administered, while recovering and measuring analytes in breath samples. The cannula may connect to a portable processor-display unit for monitoring one or more analytes, such as CO2. Another embodiment includes a cannula configured for the monitoring of sleep disorders, such as apnea, comprising one or more sensors disposed adjacent a breath sampling channel, optionally including flow rate or other sensors. The sensors may be connected by wired or wireless links for to a processor/input/display unit. Any of the embodiments may include filters, selectively permeable membranes, absorbents, and the like to precondition the breath sample, may be configured to include complementary chemistry measurements.

    • A nanoelectronic sensing device includes a substrate, a nanostructure element disposed adjacent the substrate, and at least a conductive element electrically connected to the nanostructure element. The device is configured to heat at least a portion of the sensor structure including the nanostructure element. In certain embodiments, the nanostructure element comprises at least one nanotube, the nanotube being electrically connected to at least two conductors so as to permit an electric current on the order of 10 microAmps or greater to be passed through the nanotube, causing the nanotube to heat up relative to the substrate. In alternative embodiments, the sensing device includes a platform or membrane which is at least partially thermally isolated by one or more cavities, the platform supporting at least the nanostructure element adjacent to a microheater element. The heating of the sensor structure may be employed, for example, for thermoregulation, to accelerate and/or increase sensor response, and to improve other sensor characteristics.
