摘要： Nanostructure sensing devices for detecting an analyte are described. The devices include nanostructures connected to conductive elements, all on a substrate. Contact regions adjacent to points of contact between the nanostructures and the conductive elements are given special treatment. The proportion of nanostructure surface area within contact regions can be maximized to effect sensing at very low analyte concentrations. The contact regions can be passivated in an effort to prevent interaction between the environment and the contact regions for sensing at higher analyte concentrations and for reducing cross-sensing. Both contact regions and at least some portion of the nanostructures can be covered with a material that is at least partially permeable to the analyte of interest and impermeable to some other species to tune selectivity and sensitivity of the nanostructure sensing device.

摘要： A nanostructure sensing device includes a substrate, a nanotube disposed over the substrate, and at least two conductive elements electrically connected to the nanotube. A electric current on the order of about 10 μA, or greater, is passed through the conductive elements and the nanotube. As a result, the nanotube heats up relative to the substrate. In the alternative, some other method may be used to heat the nanotube. When operated as a sensor with a heated nanotube, the sensor's response and/or recovery time may be markedly improved.

摘要： An electronic system for selectively detecting and identifying a plurality of chemical species, which comprises an array of nanostructure sensing devices, is disclosed. Within the array, there are at least two different selectivities for sensing among the nanostructure sensing devices. Methods for fabricating the electronic system are also disclosed. The methods involve modifying nanostructures within the devices to have different selectivity for sensing chemical species. Modification can involve chemical, electrochemical, and self-limiting point defect reactions. Reactants for these reactions can be supplied using a bath method or a chemical jet method. Methods for using the arrays of nanostructure sensing devices to detect and identify a plurality of chemical species are also provided. The methods involve comparing signals from nanostructure sensing devices that have not been exposed to the chemical species of interest with signals from nanostructure sensing devices that have been exposed to the chemical species of interest.
