  • Publication number: 20200115671
    Abstract: Disclosed herein are apparatus and methods to perform in-vitro probing of cell interior using a nanoneedle. Some aspects of the present application relate to an apparatus with a vertical nanoneedle disposed in a flow channel, wherein the flow channel is shaped to facilitate immobilization of a cell recirculating in a fluid in the flow channel with the nanoneedle and penetration of the cell membrane with the nanoneedle. Aspects of the present application also provide an integration between the flow channel and a cell sorter to form a medical system that selectively and continuously communicates intracellularly with screened cells of interests.

  • Publication number: 20180217076
    Abstract: A nanoscale probe includes a substrate and a pair of nanoscale wires each having a first end disposed on the substrate and a second end. The second ends of each nanoscale wire are in contact with one another such that the pair of nanoscale wires form a bridge extending over the substrate. The nanoscale wires may be electrically connected to electrodes residing on the substrate. The electrodes, in turn, are connected to an active electronic device such as a readout device or microprocessor formed in the substrate on which the probe is located. In this way a property of the nanoscale wires, and thus of the cell, may be determined.

  • Patent number: 9381355
    Abstract: A prosthetic retina for implantation in an eye having a defective retina is formed from an array of nanowires having a predetermined spatial distribution, density, size and shape implanted in close proximity to the retina. An electrical conductor is formed at a first end of all nanowires in the array of nanowires and placed in contact with a bias source which biases the array. A plurality of electrodes is located on a second end of each of one nanowire or a bundle of nanowires in the array. Each nanowire produces a photocurrent at a corresponding electrode in response to detection of light impinging on the array of nanowires and the photocurrent stimulates one or more neurons adapted for visual perception. In the preferred embodiment, the predetermined spatial distribution mimics a distribution of rods and cones in a normal eye.

    Abstract: Embodiments provide a nanoparticle and a method for preparing the nanoparticle, as well as a membrane that includes the nanoparticle and a fuel cell that includes the membrane. The method comprises a thermal treatment method that provides from a nanoparticle comprising a structurally disordered material the nanoparticle comprising: (1) a structurally ordered core comprising a first material; and (2) a shell surrounding and further structurally aligned with the structurally ordered core and comprising a second material different from the first material. Particularly desirable is a nanoparticle comprising a Pt3Co@Pt/C structurally ordered core-shell composition supported upon a carbon support.

  • Patent number: 9024295
    Abstract: A 1D nanowire photodetector device includes a nanowire that is individually contacted by electrodes for applying a longitudinal electric field which drives the photocurrent. An intrinsic radial electric field to inhibits photo-carrier recombination, thus enhancing the photocurrent response. Circuits of 1D nanowire photodetectors include groups of photodetectors addressed by their individual 1D nanowire electrode contacts. Placement of 1D nanostructures is accomplished with registration onto a substrate. A substrate is patterned with a material, e.g., photoresist, and trenches are formed in the patterning material at predetermined locations for the placement of 1D nanostructures. The 1D nanostructures are aligned in a liquid suspension, and then transferred into the trenches from the liquid suspension. Removal of the patterning material places the 1D nanostructures in predetermined, registered positions on the substrate.

  • Patent number: 8932940
    Abstract: Embodiments of the invention provide a method for direct heteroepitaxial growth of vertical III-V semiconductor nanowires on a silicon substrate. The silicon substrate is etched to substantially completely remove native oxide. It is promptly placed in a reaction chamber. The substrate is heated and maintained at a growth temperature. Group III-V precursors are flowed for a growth time. Preferred embodiment vertical Group III-V nanowires on silicon have a core-shell structure, which provides a radial homojunction or heterojunction. A doped nanowire core is surrounded by a shell with complementary doping. Such can provide high optical absorption due to the long optical path in the axial direction of the vertical nanowires, while reducing considerably the distance over which carriers must diffuse before being collected in the radial direction. Alloy composition can also be varied. Radial and axial homojunctions and heterojunctions can be realized. Embodiments provide for flexible Group III-V nanowire structures.

  • Patent number: 8847476
    Abstract: Embodiments of the invention include methods and devices for producing light by injecting electrons from field emission cathode across a gap into nanostructured semiconductor materials, electrons issue from a separate field emitter cathode and are accelerated by a voltage across a gap towards the surface of the nanostructured material that forms part of the anode. At the nanostructure material, the electrons undergo electron-hole (e-h) recombination resulting in electroluminescent (EL) emission. In a preferred embodiment lighting device, a vacuum enclosure houses a field emitter cathode. The vacuum enclosure also houses an anode that is separated by a gap from said cathode and disposed to receive electrons emitted from the cathode. The anode includes semiconductor light emitting nano structures that accept injection of electrons from the cathode and generate photons in response to the injection of electrons.
