20080292840 | Electrically and thermally conductive carbon nanotube or nanofiber array dry adhesive - A two-sided carbon nanostructure thermal interface material having a flexible polymer matrix; an array of vertically aligned carbon nanostructures on a first surface of the flexible polymer matrix; and an array of vertically aligned carbon nanostructures on a second surface of the flexible polymer matrix, wherein the first and second surfaces are opposite sides of the flexible polymer matrix. | 11-27-2008 |
20090011946 | Use of Sequence Specific Polymers in Chemical Detection - A method for chemical detection is provided. In one aspect, the method comprises exposing a sample to a sequence specific polymer under conditions such that an analyte in the sample binds to the polymer. Binding of the analyte to the sequence specific polymer results in a change in a property of the sequence specific polymer that is transduced to a response transduction medium, which generates a detectable response. Another aspect provides a detection device comprising the sequence specific polymer and response transduction medium. | 01-08-2009 |
20090056917 | NANOSTRUCTURED MICRO HEAT PIPES - A heat pipe comprising a chamber; a wick in the chamber, and a heat sink, which is adjacent to a first portion of the wick. A heat source adjacent to a second portion of the wick, wherein the wick is configured such that a gas condenses at the first portion of the wick and a liquid evaporates at the second portion of the wick. The fluid moves from the first portion of the wick to the second portion of the wick, and wherein the wick comprises nanostructures having a differentially-spaced apart gradient along the length of the wick so as to promote capillary fluid flow therealong. | 03-05-2009 |
20100003516 | METHODS OF FABRICATING NANOSTRUCTURES AND NANOWIRES AND DEVICES FABRICATED THEREFROM - One-dimensional nanostructures having uniform diameters of less than approximately 200 nm. These inventive nanostructures, which we refer to as “nanowires”, include single-crystalline homostructures as well as heterostructures of at least two single-crystalline materials having different chemical compositions. Because single-crystalline materials are used to form the heterostructure, the resultant heterostructure will be single-crystalline as well. The nanowire heterostructures are generally based on a semiconducting wire wherein the doping and composition are controlled in either the longitudinal or radial directions, or in both directions, to yield a wire that comprises different materials. Examples of resulting nanowire heterostructures include a longitudinal heterostructure nanowire (LOHN) and a coaxial heterostructure nanowire (COHN). | 01-07-2010 |
20100233029 | COMPENSATED MEMBRANE CAPACITIVE BIO-CHEMICAL SENSOR - A sensor having a membrane, which is adapted to deflect in response to a change in surface stress. The membrane has a first and a second surface, which includes a first coating layer on the first surface of the membrane, and a second coating layer on the second surface of the membrane. The first coating layer is adapted to couple one or more probe molecules with the membrane. | 09-16-2010 |
20110168968 | FLUIDIC NANOTUBES AND DEVICES - Fluidic nanotube devices are described in which a hydrophilic, non-carbon nanotube, has its ends fluidly coupled to reservoirs. Source and drain contacts are connected to opposing ends of the nanotube, or within each reservoir near the opening of the nanotube. The passage of molecular species can be sensed by measuring current flow (source-drain, ionic, or combination). The tube interior can be functionalized by joining binding molecules so that different molecular species can be sensed by detecting current changes. The nanotube may be a semiconductor, wherein a tubular transistor is formed. A gate electrode can be attached between source and drain to control current flow and ionic flow. By way of example an electrophoretic array embodiment is described, integrating MEMs switches. A variety of applications are described, such as: nanopores, nanocapillary devices, nanoelectrophoretic, DNA sequence detectors, immunosensors, thermoelectric devices, photonic devices, nanoscale fluidic bioseparators, imaging devices, and so forth. | 07-14-2011 |
