  • Patent number: 7147441
    Abstract: Microfluidic channels utilizing magnetohydrodynamics are used to pump very small volumes of solution. The channels have electrodes along the walls of the channel and a current carrying species within the solution carries the current through the solution. The electric field generated by the use of the current carrying species is perpendicular to a magnetic field applied to the channel. The combination of the electric and magnetic fields causes the solution to flow through the channel.

  • Patent number: 7144486
    Abstract: Microcavities and micropores that are microscopic (<1 mm) in width and depth and contain any number of individually-addressable electrodes, separated by insulators, along the walls of each cavity. The conducting materials, and the insulator materials can be deposited alternately onto a starting substrate, which is typically an oxidized silicon wafer or polyimide film, but may be any substrate that shows good adhesion to the materials layered on it. The cavities are etched through these layers, perpendicular to the plane of the substrate, exposing the layers at their edges. Pores may be carved entirely through the device.

  • Publication number: 20060246421
    Abstract: The inventors have discovered that an ATPase-deficient dominant-negative mutant NS3 protein of hepatitis C virus inhibits activity of the wild-type NS3 protein and inhibits replication of hepatitis C virus (HCV). The solved crystal structure of a multi-enzyme NS3 complex on a DNA substrate is also provided. The inventors have tested a peptide matching the sequence of a portion of NS3 that interacts with another NS3 molecule for inhibiting HCV replication. The peptide inhibits HCV replication. Accordingly, the invention provides a method of inhibiting HCV replication in cells infected with HCV involving transforming the cells with a vector expressing a dominant-negative mutant NS3 gene. The invention also provides a method of inhibiting HCV replication in cells infected with HCV involving administering to the cells a dominant-negative mutant NS3 protein. The invention also provides peptides and agents that inhibit HCV replication and methods of identifying agents that inhibit HCV replication.

  • Patent number: 7105051
    Abstract: The present invention provides substantially monodisperse colloidal nanocrystals and new preparative methods for the synthesis of substantially monodisperse colloidal nanocrystals. These synthetic methods afford the ability to tune nanocrystal size and size distribution. By using non-coordinating solvents in the synthetic process, these procedures constitute easier, less expensive, safer, and more environmentally “green” methods than those currently in use. This invention is generally applicable to any II–VI or III–V semiconductor material, and may be useful in generating metal-nonmetal compounds involving transition metals as well.

  • Patent number: 7049175
    Abstract: A structure and process for packaging RF MEMS and other devices employs a substrate of silicon, for example, and a cap of glass, for example, having cavities to receive the devices. MEMS or other devices are supported on an upper surface of the substrate, into which metal-filled blind vias are formed. The cap is attached to the substrate, so as to enclose designated MEMS or other devices in the cavities. The substrate is then thinned so as to expose the metal of the vias at a lower surface of the substrate. Electrical connecting elements such as solder balls are then applied to the metal of the vias. The resultant composite substrate is then divided to provide individual packaged devices.
