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： 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 flexible electronic device is made up of nanostructures. Specifically, the device includes a flexible substrate, a film of nanostructures in contact with the flexible substrate, a first conducting element in contact with the film of nanostructures, and a second conducting element in contact with the film of nanostructures. The nanostructures may comprise nanotubes, such as carbon nanotubes disposed along the flexible substrate, such as an organic or polymer substrate. The first and second conductive elements may serve as electrical terminals, or as a source and drain. In addition, the electronic device may include a gate electrode that is in proximity to the nanotubes and not in electrical contact with the nanotubes. In this configuration, the device can operate as a transistor or a FET. The device may also be operated in a resistive mode as a chemical sensor (e.g., for sensing NH3).
