Abstract: A sensor for detection of target nucleic acid comprising (a) a semiconductor nanostructure; and (b) a nucleic acid detection probe immobilized on the semiconductor nanostructure capable of hybridizing with the target nucleic acid, the detection probe comprising a polymer with a substantially non-ionic backbone.

Abstract: A PRAM device includes a lower electrode, a phase-change nanowire and an upper electrode. The phase-change nanowire may be electrically connected to the lower electrode and includes a single element. The upper electrode may be electrically connected to the phase-change nanowires.

Abstract: A method of synthesizing silicon wires generally includes the steps of: providing a substrate; forming a copper catalyst particle layer on a top surface of the substrate; heating the reactive device at a temperature of above 450° C. in a flowing protective gas; and introducing a mixture of a protective gas and a silicon-based reactive gas at a temperature of above 450° C. at a pressure of below 700 Torr, thereby forming the silicon wires on the substrate.

Abstract: Disclosed herein is an article comprising a nucleic acid-carbon nanotube molecular composite in selective communication with at least one of a plurality of material phases; the selective communication being the result of an affinity of functional groups present in the nucleic acid-carbon nanotube molecular composite for the at least one of the plurality of material phases; the material phases being at least a part of a substrate; the nucleic acid-carbon nanotube molecular composite comprising at least one of i) a nucleic acid disposed on a functionalized carbon nanotube; ii) a functionalized nucleic acid disposed on a carbon nanotube; and iii) a functionalized nucleic acid disposed on a functionalized carbon nanotube to form a nucleic acid-carbon nanotube molecular composite.

Abstract: The invention provides multisegmented, multifunctional magnetic nanowires for the probing and manipulation of molecules at the cellular and subcellular level. The different segments of the nanowire may have differing properties, including a variety of magnetic, non-magnetic, and luminescent behavior. Differences in surface chemistry allow different segments of a single nanowire to be functionalized with different multiple functional groups and/or ligands, giving the wire chemical multifunctionality.
