  • Publication number: 20090165533
    Abstract: 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 ?A, 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.

  • Publication number: 20090101996
    Abstract: 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.

  • Publication number: 20060263255
    Abstract: A new sensing technology for chemical/biomolecular sensors is provided. One such sensor detects molecular hydrogen (H2) using nanoelectronic components. A tiny, low-cost nanosensor chip can offer: (i) performance that matches or exceeds that of existing technology, (ii) plug-and-play simplicity with both digital and analog control systems, and (ii) the small size and low power consumption needed for wireless integration.

  • Publication number: 20060204427
    Abstract: Certain applicator liquids and method of making the applicator liquids are described. The applicator liquids can be used to form nanotube films or fabrics of controlled properties. An applicator liquid for preparation of a nanotube film or fabric includes a controlled concentration of nanotubes dispersed in a liquid medium containing water. The controlled concentration is sufficient to form a nanotube fabric or film of preselected density and uniformity.
