    摘要: A method is provided for selectively placing catalytic nanoparticles (22) for growing one dimensional structures (28) including nanotubes and nanowires. The method comprises providing a solution (23) including a plurality of catalytic nanoparticles (28) suspended therein. An alternating current is applied between two electrodes (12, 14) submersed in the solution (23), thereby positioning the plurality of catalytic nanoparticles (22) contiguous to the two electrodes (12, 14). A one dimensional nanostructure (28) is then grown from each of the catalytic nanoparticles (22).

    摘要: A device is provided for determining the degree of the presence of an unwanted environmental agent. The apparatus comprises a device (30, 40) having first (31, 41) and second (33, 46) conducting layers with alternatively interdigitized fingers (34, 36, 42, 43, 44, 47, 48, 49) coupled to a nano-structure (32, 45) having a high aspect ratio, wherein sections (35, 37, 50, 51, 52, 53, 54) of the nano-structure between each of the fingers are substantially equal in length. Circuitry (62) coupled to the first and second conducting layers determines the occurrence of a change in a material characteristic of the sections of the nano-structure.
