    摘要: Provided are methods for synthesizing metal nanowires in solution using an organic reducing agent. A reaction mixture can be provided in solution with a metal salt, the organic reducing agent, and a solvent, where the solvent includes a surface ligand or consists of a surface ligand. The organic reducing agent, such as benzoin, can be decomposed in the reaction mixture to form organic free radicals that reduce metal ions of the metal salt into metal. The surface ligand of the solvent can coordinate with the metal in a manner so that metal nanowires are formed in solution. The diameter and morphology of the nanowires, reaction speed, reaction yield, and other features may be tunable by adjusting parameters such as reaction temperature and chemistry of the reducing agent.

    摘要: A functionalized nanofluidic channel and method for functionalization that provides control over the ionic environment and geometry of the nanofluidic channel with the immobilization of biomolecules on the inner surface of the channel and use of high ionic concentration solutions. In one embodiment, the surface charge of the nanochannel is controlled with the immobilization of a protein such as streptavidin in the nanochannel. In another embodiment, the biomolecules are receptors and changes in nanochannel conductance indicates ligand binding events. The functionalized nanofluidic channel can be easily adapted for use with microchannel arrays.

    摘要: Methods for assembly of monolayers of nanoparticles using the Langmuir-Blodgett technique, as well as monolayers, assemblies, and devices are described. The surface properties of these monolayers are highly reproducible and well-defined as compared to other systems. These monolayers can readily be used for molecular detection in either an air-borne or a solution environment, and sensors using the monolayer could have significant implications in chemical and biological warfare detection, national and global security, as well as in medical detection applications.

    摘要: Novel and significantly simplified procedures for fabrication of fully integrated nanoelectrospray emitters have been described. For nanofabricated monolithic multinozzle emitters (NM 2 emitters), a bottom up approach using silicon nanowires on a silicon sliver is used. For microfabricated monolithic multinozzle emitters (M 3 emitters), a top down approach using MEMS techniques on silicon wafers is used. The emitters have performance comparable to that of commercially-available silica capillary emitters for nanoelectrospray mass spectrometry.

    摘要: A method for controlling the crystallographic growth direction and geometric and physical characteristics of nanowires using a metal-organic chemical vapor deposition and substrate selection. As an illustration of the method, epitaxial growth of wurtzite gallium nitride on (100) y -LiAIO 2 and (111) MgO single crystal substrates resulted in the selective growth of nanowires in the orthogonal [110] and [001] directions, respectively. Triangular and hexagonal cross sections were observed as a result of substrate-induced constraints of lattice parameter matching and symmetry registry. These nanowire arrays exhibit a systematic difference in their temperature­ dependent band-edge emission resulting from the different size, shape, and anisotropic polarity of the nanostructures. Scaling of the synthetic process is entirely compatible with existing GaN thin-film technology and should enable the realization of a new generation of GaN nanowire devices and systems.

    摘要: Methods of fabricating uniform nanotubes are described in which nanotubes were synthesized as sheaths over nanowire templates, such as using a chemical vapor deposition process. For example, single-crystalline zinc oxide (ZnO) nanowires are utilized as templates over which gallium nitride (GaN) is epitaxially grown. The ZnO templates are then removed, such as by thermal reduction and evaporation. The completed single-crystalline GaN nanotubes preferably have inner diameters ranging from 30 nm to 200 nm, and wall thicknesses between 5 and 50 nm. Transmission electron microscopy studies show that the resultant nanotubes are single-crystalline with a wurtzite structure, and are oriented along the direction. The present invention exemplifies single-crystalline nanotubes of materials with a non-layered crystal structure. Similar "epitaxial-casting" approaches could be used to produce arrays and single-crystalline nanotubes of other solid materials and semiconductors. Furthermore, the fabrication of multi-sheath nanotubes are described as well as nanotubes having multiple longitudinal segments.
