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.

摘要： Systems and methods to fabricate macroelectronic light emitting devices using densely oriented nanowires are disclosed. In one embodiment, core nanowires are synthesized and an insulating shell is fabricated around the nanowires. The nanowire core-shell structures are then deposited on a substrate to create a densely oriented nanowire thin film. Once the densely oriented nanowire thin film is created, a metal-insulator nanowire structure is fabricated by layering a metal on the nanowire thin film. Ohmic contacts are then created on the metal-insulator nanowire structure for operation. Application of electrical signals to the ohmic contacts causes light emission from the metal-insulator nanowire structure. Light emitting devices having densely oriented nanowire thin films are also disclosed. In an embodiment the light emitting device is, for example, a LED. The nanowires can include, for example, GaN, InP, CdS nanowires or a combination of these and other nanowires. Different colors of light can be produced based on the type of nanowire, the combination of nanowire types and the physical characteristics of the nanowires.
