摘要:
Methods of detecting components of interest, e.g., nucleic acids and sugars, are provided. The methods comprise contacting one or more nanowires comprising a functional group with a sample containing the component or components of interest. In one embodiment, the functional group comprises a hairpin oligonucleotide, e.g., a hairpin that changes conformation upon binding the component of interest, e.g., a nucleic acid. The change in conformation produces a change in charge that is detected. In another embodiment, the functional group comprises an enzyme, e.g., glucose oxidase, which produces a change in pH when glucose is present in a sample.

A method and apparatus for an electronic substrate having a plurality of semiconductor devices is described. A thin film of nanowires is formed on a substrate. The thin film of nanowires is formed to have a sufficient density of nanowires to achieve an operational current level. A plurality of semiconductor regions are defined in the thin film of nanowires. Contacts are formed at the semiconductor device regions to thereby provide electrical connectivity to the plurality of semiconductor devices. Furthermore, various materials for fabricating nanowires, thin films including p-doped nanowires and n-doped nanowires, nanowire heterostructures, light emitting nanowire heterostructures, flow masks for positioning nanowires on substrates, nanowire spraying techniques for depositing nanowires, techniques for reducing or eliminating phonon scattering of electrons in nanowires, and techniques for reducing surface states in nanowires are described.

This invention provides composite materials comprising nanostructures (e.g., nanowires, branched nanowires, nanotetrapods, nanocrystals, and nanoparticles). Methods and compositions for making such nanocomposites are also provided, as are articles comprising such composites. Waveguides and light concentrators comprising nanostructures (not necessarily as part of a nanocomposite) are additional features of the invention.
