The present invention discloses nanowires for use in a fuel cell comprising a metal catalyst deposited on a surface of the nanowires. A membrane electrode assembly for a fuel cell is disclosed which generally comprises a proton exchange membrane, an anode electrode, and a cathode electrode, wherein at least one or more of the anode electrode and cathode electrode comprise an interconnected network of the catalyst supported nanowires. Methods are also disclosed for preparing a membrane electrode assembly and fuel cell based upon an interconnected network of nanowires.

This invention provides nanowire based molecular sensors and methods for detecting analytes in a microfluidic system. Methods for sensing analytes include detecting changed electrical parameters associated with contact of a nanowire with the analyte in a microfluidic system. Sensors of the invention include nanowires mounted in microchambers of a microfluidic system in electrical contact with the detector, whereby electrical parameter changes induced in the nanowire by the analyte can be monitored by the detector.

Nanowire-based sensor configurations

The present invention relates to a system and process for producing a nanowire-material composite. A substrate having nanowires attached to a portion of at least one surface is provided. A material is deposited over the portion to form the nanowire-material composite. The process further optionally includes separating the nanowire-material composite from the substrate to form a freestanding nanowire-material composite. The freestanding nanowire material composite is optionally further processed into a electronic substrate. A variety of electronic substrates can be produced using the methods described herein. For example, a multi-color light-emitting diode can be produced from multiple, stacked layers of nanowire-material composites, each composite layer emitting light at a different wavelength.

Methods for determining total analyte concentrations and amounts, especially in combination with analyte separations are provided. Microfluidic devices are used to separate analyte mixtures and detect the individual analytes. Signal areas are summed for each individual analyte to quantitate the total analyte amount. Separate measurements of the total analyte sample are also used to determine total analyte concentration.

Total analyte quantitation

Nanocomposite photovoltaic devices are provided that generally include semiconductor nanocrystals as at least a portion of a photoactive layer. Photovoltaic devices and other layered devices that comprise core-shell nanostructures and/or two populations of nanostructures, where the nanostructures are not necessarily part of a nanocomposite, are also features of the invention. Varied architectures for such devices are also provided including flexible and rigid architectures, planar and non-planar architectures and the like, as are systems incorporating such devices, and methods and systems for fabricating such devices. Compositions comprising two populations of nanostructures of different materials are also a feature of the invention.

Nanostructure and nanocomposite based compositions and photovoltaic devices

Methods and apparatuses for nanoenabled memory devices and anisotropic charge carrying arrays are described. In an aspect, a memory device includes a substrate, a source region of the substrate, and a drain region of the substrate. A population of nanoelements is deposited on the substrate above a channel region, the population of nanolements in one embodiment including metal quantum dots. A tunnel dielectric layer is formed on the substrate overlying the channel region, and a metal migration barrier layer is deposited over the dielectric layer. A gate contact is formed over the thin film of nanoelements. The nanoelements allow for reduced lateral charge transfer. The memory device may be a single or multistate memory device. In a multistate memory device which comprises one or more quantum dots or molecules having a plurality of discrete energy levels, a method is disclosed for charging and/or discharging the device which comprises filling each of the plurality of discrete energy levels of each dot or molecule with one or more electrons, and subsequently removing individual electrons at a time from each discrete energy level of the one or more dots or molecules.

Fluid introduction is facilitated through the use of a port which extends entirely through a microfluidic substrate. Capillary forces can be used to retain the fluid within the port, and a series of samples or other fluids may be introduced through a single port by sequentially blowing the fluid out through the substrate and replacing the removed fluid with an alternate fluid, or by displacing the fluid in part with additional fluid. In another aspect, microfluidic substrates have channels which varying in cross-sectional dimension so that capillary action spreads a fluid only within a limited portion of the channel network. In yet another aspect, the introduction ports may include a multiplicity of very small channels leading from the port to a fluid channel, so as to filter out particles or other contaminants which might otherwise block the channel at the junction between the channel and the introduction port.
