  • Patent number: 6750065
    Abstract: Immunoassay displacement methods for detecting (preferably identifying) the presence or amount of a target analyte (e.g. drug) in a sample comprising the steps of: (a) exposing the sample to a complex comprising an immobilized antibody capable of specifically binding the analyte, said antibody being specifically bound to a displacement agent, wherein said agent comprises: (I) an analyte analog capable of specifically binding the antibody, (ii) a surface enhanced resonance raman scattering (SERRS) or a surface enhanced raman scattering (SERS) active label, (iii) a SERRS or SERS surface-seeking group (e.g. benztriazole), whereby any analyte present in the sample causes the displacement of agent from the antibody; (b) exposing any displaced agent to a SERRS or SERS surface; and, (c) detecting any displaced agent associated with said surface using SERRS or SERS.

  • Patent number: 6715568
    Abstract: The use of polymer latices is described for fluid loss control in water-based drilling fluids. The latices used are water insoluble. The latices are essentially non-swelling in an aqueous solution. The latices are selected from known latices such that they are absorbed within a filter cake building up at the interface between the wellbore and porous formations in essentially the same state as they are in the aqueous drilling fluid during circulation.

  • Patent number: 6717819
    Abstract: A solderable flexible adhesive interposer having solderable contacts includes low-modulus-of-elasticity (i.e. molecularly flexible) conductive adhesive vias to which contacts of an electronic device, such as a semiconductor chip or die or other component, are connected. The flexible adhesive interposer substrate includes a sheet or layer of a molecularly flexible dielectric adhesive having via holes therein through which the flexible conductive adhesive vias reside. A thin layer of solderable metal, preferably a plating of gold or nickel-gold, on at least one exposed surface of the flexible conductive adhesive vias provides the solderable contacts connecting electrically to the conductive vias. The electronic device may be covered by a lid or by an encapsulant attached to the flexible adhesive interposer substrate and/or the electronic device.

  • Patent number: 6709862
    Abstract: A method and apparatus for aseptic biological production of cells and/or microorganisms are provided. The apparatus includes a support housing having an interior chamber, a disposable flexible sterile plastic liner lining the interior chamber and a head plate attached to the liner forming a sealed chamber with the liner to form a reservoir. After use the liner can be thrown away and the apparatus can be reused with a new liner. In this way, the apparatus simplifies cleaning and ensuring validation required by pharmaceutical and food industry standards. Aerating fluid is introduced during culturing of cell or microorganisms in the reservoir. A growth characteristic can be used to vary flow rate and/or composition of the aerating fluid. Another reservoir may be used for circulation between two reservoirs.

  • Patent number: 6692390
    Abstract: A plastic movable guide is disclosed wherein a reinforcing plate for reinforcing a guide body is simplified in shape, permitting easy assembly and prevention of disengagement. The movable guide is constituted by a guide body and a reinforcing plate fitted into the guide body. The guide body has a slit which receives the reinforcing plate which has a pair of recesses. A pair of windows are formed in the guide body to register with the reinforcing plate recesses. Each window has a tongue piece having a face which projects angularly into the slit and terminates in a retaining portion. When the reinforcing plate is advanced into the slit, the retaining portions of the tongue pieces are deflected out of the slit and when the plate is seated, the retaining portions are engaged in the recesses and retain the plate in the guide body.

  • Patent number: 6685809
    Abstract: A microfabricated device employing a bridging membrane and methods for electrokinetic transport of a liquid phase biological or chemical material using the same are described. The bridging membrane is deployed in or adjacent to a microchannel and permits either ionic current flow or the transport of gas species, while inhibiting the bulk flow of material. The use of bridging membranes in accordance with this invention is applicable to a variety of processes, including electrokinetically induced pressure flow in a region of a microchannel that is not influenced by an electric field, sample concentration enhancement and injection, as well as improving the analysis of materials where it is desired to eliminate electrophoretic bias. Other applications of the bridging membranes according to this invention include the separation of species from a sample material, valving of fluids in a microchannel network, mixing of different materials in a microchannel, and the pumping of fluids.
