John B. Troy has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Electrode for whole cell and other testing
    Patent number: 8557095
    Abstract: A pushpen electrode is provided for electrophysiology measurements. The pushpen operation is used to impale a cell membrane in cell-attached configuration to go whole-cell without disruption of the gigaseal. The pushpen electrode has advantages over the conventional patch clamp electrode in reducing tip series resistance, increasing signal bandwidth, permitting longer-term recordings and reducing diffusion between the cytosol and the electrode solution.
    Type: Grant

    Date of Patent: October 15, 2013
    Assignee: Northwestern University
    Inventors: John B. Troy, Samsoon Inayat, Donald R. Cantrell, Yan Zhao, Dmitriy A. Dikin
