    摘要： A portable sensor device incorporates a low-power, nanostructure sensor coupled to a wireless transmitter. The sensor uses a nanostructure conducting channel, such as a nanotube network, that is functionalized to respond to a selected analyte. A measurement circuit connected to the sensor determines a change in the electrical characteristic of the sensor, from which information concerning the present or absence of the analyte may be determined. The portable sensor device may include a portable power source, such as a battery. It may further include a transmitter for wirelessly transmitting data to a base station.

    摘要： A detector system is described including arrays having a plurality of nanoelectronic sensors comprising a channel including a nanostructured element disposed on a substrate, the nanostructured element functionalized by one or more materials disposed on or adjacent to the nanostructured element so as to operatively influence one or more sensor electrical properties. In certain embodiments, the nanostructured element comprise one or more nanotubes, and the functionalization material may include nanoparticles composed of one or more metals, metal oxides, salts, or other inorganic or organic materials or composites of these.In one exemplary embodiment, an array includes plurality of sensors which are configured as field effect transistors, the nanostructured element comprising a randomly dispersed interconnecting network of single-walled carbon nanotubes (SWNTs) having semiconducting properties, and functionalized by deposition of metallic nanoparticles comprising one or more metallic elements. The deposition of nanoparticles may be controlled to preserve semiconductive properties of the nanotubes. Novel methods of electrodeposition of such nanoparticles are described.The detector system may be configured to distinguish and detect a range of different analyte species by measurement of the responses of a plurality of sensors of the array, and analyzing the measurements using principal component analysis, pattern-recognition analysis tools, and the like. Example analytes may comprise a plurality of organic and inorganic gases, such as are relevant to medical, industrial, environmental and security detection.

    摘要： Embodiments of nanoelectronic sensors are described, including sensors for detecting analytes such as anesthesia gases, CO2 and the like in human breath. An integrated monitor system and disposable sensor unit is described which permits a number of different anesthetic agents to be identified and monitored, as well as concurrent monitoring of other breath species, such as CO2. The sensor unit may be configured to be compact, light weight, and inexpensive. Wireless embodiments provide such enhancements as remote monitoring. A simulator system for modeling the contents and conditions of human inhalation and exhalation with a selected mixture of a treatment agent is also described, particularly suited to the testing of sensors to be used in airway sampling.
