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.
摘要翻译：描述了用于检测分析物的纳米结构感测装置。这些器件包括连接到导电元件的纳米结构，全部在衬底上。给予与纳米结构和导电元件之间的接触点相邻的接触区域的特殊处理。可以使接触区域内的纳米结构表面积的比例最大化，以在非常低的分析物浓度下进行感测。可以钝化接触区域，以防止环境和接触区域之间的相互作用，以便在较高分析物浓度下进行感测并减少交叉感测。两个接触区域和纳米结构的至少一部分可以被对感兴趣的分析物至少部分可渗透的材料覆盖，并且对于一些其它物质是不可渗透的，以调节纳米结构感测装置的选择性和灵敏度。

摘要： A nanoelectronic device includes a nanostructure, such as a nanotube or network of nanotube, disposed on a substrate. Nanoparticles are disposed on or adjacent to the nanostructure so as to operatively effect the electrical properties of the nanostructure. The nanoparticles may be composed of metals, metal oxides or salts and nanoparticles composed of different materials may be present. The amount of nanoparticles may be controlled to preserve semiconductive properties of the nanostructure, and the substrate immediately adjacent to the nanostructure may remain substantially free of nanoparticles. A method for fabricating the device includes electrodeposition of the nanoparticles using one of more solutions of dissolved ions while providing an electric current to the nanostructures but not to the surrounding substrate.
