  • Patent number: 10335791
    Abstract: Methods for detecting target analytes utilizing an array of wells are advantageous for detection of low concentrations of target analytes. Use of an array of wells requires sealing of the wells. The methods provided herein utilize digital microfluidics to seal wells of an array with a fluid that is immiscible with the aqueous liquid present in the wells to prevent evaporation and contamination of the aqueous fluid during analysis of signals from the wells. The disclosed method include generating a biphasic droplet composed of the immiscible fluid and an aqueous fluid. The immiscible fluid present in the biphasic droplet is moved over the array of wells to seal the wells by electrically actuating the aqueous fluid present in the biphasic droplet which in turn pulls the immiscible fluid.

  • Patent number: 10150058
    Abstract: Emulsion breaking and phase separation is achieved by droplet adhesion. An emulsion breaking device includes a channel having distinct adjacent zones with distinctly different surface wettability characteristics, namely, solvophilic and solvophobic surfaces. The device is positioned such that the upstream portion of the device is configured to be wetted by the continuous phase of the emulsion, and the downstream portion of the device is configured to be wetted by the dispersed phase of the emulsion. As the emulsion flows from the upstream zone to the downstream zone, the change in surface wettability characteristics promotes adhesion of the dispersed phase as the dispersed phase wets the surface of the downstream portion of the channel, which results in breaking of the emulsion. Subsequent collection of the broken emulsion in a collection vessel results in separation of the disparate phases to facilitate their recapture and recycling.

  • Patent number: 10113195
    Abstract: In some embodiments, the present teachings provide methods for nucleic acid amplification, comprising forming a reaction mixture, and subjecting the reaction mixture to conditions suitable for nucleic acid amplification. In some embodiments, methods for nucleic acid amplification include subjecting the nucleic acid to be amplified to partially denaturing conditions. In some embodiments, methods for nucleic acid amplification include amplifying without fully denaturing the nucleic acid that is amplified. In some embodiments, the methods for nucleic acid amplification employ an enzyme that catalyzes homologous recombination and a polymerase. In some embodiments, methods for nucleic acid amplification can be conducted in a single reaction vessel. In some embodiments, methods for nucleic acid amplification can be conducted in a single continuous liquid phase of a reaction mixture, without need for compartmentalization of the reaction mixture or immobilization of reaction components.

  • Patent number: 10105700
    Abstract: The present invention describes an integrated apparatus that enables identification of migratory cells directly from a specimen. The apparatus only requires a small number of cells to perform an assay and includes novel topographic features which can reliably differentiate between migratory and non-migratory cell populations in a sample. Both the spontaneous and chemotactic migration of cancer cells may be measured to distinguish between subpopulations within a tumor sample. The migratory cells identified using the apparatus and methods of the present invention may be separated and further analyzed to distinguish factors promoting metastasis within the population. Cells in the apparatus can be treated with chemotherapeutic or other agents to determine drug strategies to most strongly inhibit migration. The use of optically transparent materials in some embodiments allows a wide range of imaging techniques to be used for in situ imaging of migratory and non-migratory cells in the apparatus.

  • Patent number: 10099927
    Abstract: A process for derivatization of an elemental carbon surface comprising exposing the carbon surface to a reaction mixture containing a thiol and a free radical initiator, and inducing decomposition of the initiator to free radicals so that moieties from the thiol become covalently attached to the carbon surface. The process can derivatize carbon with a redox active compound having a functional group which can be converted electrochemically between reduced and oxidized forms. Such derivatized carbon may be used in an electrode of an electrochemical sensor.
