  • Publication number: 20080230387
    Abstract: A variety of elastomeric-based microfluidic devices and methods for using and manufacturing such devices are provided. Certain of the devices have arrays of reaction sites to facilitate high throughput analyses. Some devices also include reaction sites located at the end of blind channels at which reagents have been previously deposited during manufacture. The reagents become suspended once sample is introduced into the reaction site. The devices can be utilized with a variety of heating devices and thus can be used in a variety of analyses requiring temperature control, including thermocycling applications such as nucleic acid amplification reactions, genotyping and gene expression analyses.

  • Publication number: 20080108063
    Abstract: The invention provides an assay method for detection and/or quantification of a plurality of nucleic acid or protein targets in a sample. In the method probes are used to associate a detectable tag sequence with each of the selected targets present in the sample. Probes or primers sufficient to identify at least 25, and preferably at least 500, different targets are used. The method involves segregating aliquots of the sample from each other and detecting the tag sequences in each aliquot.

  • Patent number: 7291512
    Abstract: A valve structure comprises an elastomeric block formed with first and second microfabricated recesses separated by a membrane portion of the elastomeric block. The valve is actuated by positioning a compliant electrode on a first side of the first recess proximate to and in physical communication with the membrane. Where the valve is to be electrostatically actuated, a second electrode is positioned on a second side of the first recess opposite the first side. Application of a potential difference across the electrodes causes the compliant electrode and the membrane to be attracted into the flow channel. Where the valve is to be electrostrictively actuated, a second electrode is positioned on the same side of the recess as the compliant electrode. Application of a potential difference across the electrodes causes the electrodes to be attracted such that elastomer membrane portion material between them is compressed and bows into the flow channel.

  • Publication number: 20070196912
    Abstract: Methods and systems are provided for conducting a reaction at a selected temperature or range of temperatures over time. An array device is provided. The array device contains separate reaction chambers and is formed as an elastomeric block from multiple layers. At least one layer has at least one recess that recess has at least one deflectable membrane integral to the layer with the recess. The array device has a thermal transfer device proximal to at least one of the reaction chambers. The thermal transfer device is formed to contact a thermal control source. Reagents for carrying out a desired reaction are introduced into the array device. The array device is contacted with a thermal control device such that the thermal control device is in thermal communication with the thermal control source so that a temperature of the reaction in at least one of the reaction chamber is changed as a result of a change in temperature of the thermal control source.

  • Patent number: 7216671
    Abstract: A method of fabricating an elastomeric structure, comprising: forming a first elastomeric layer on top of a first micromachined mold, the first micromachined mold having a first raised protrusion which forms a first recess extending along a bottom surface of the first elastomeric layer; forming a second elastomeric layer on top of a second micromachined mold, the second micromachined mold having a second raised protrusion which forms a second recess extending along a bottom surface of the second elastomeric layer; bonding the bottom surface of the second elastomeric layer onto a top surface of the first elastomeric layer such that a control channel forms in the second recess between the first and second elastomeric layers; and positioning the first elastomeric layer on top of a planar substrate such that a flow channel forms in the first recess between the first elastomeric layer and the planar substrate.

  • Publication number: 20060093836
    Abstract: The present invention is directed to a surface modified polymer comprising a surface which is covalently bonded to a surface modifying compound. Formation of the covalent bond between the polymer and the surface modifying compound is achieved by a reaction between an intrinsic functional group that is present in the polymer and the functional group of the surface modifying compound. By using a polymer having an intrinsic functional group, a separate surface activation step is avoided.
