Mark M. Crain 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).

  • Capillary electrophoresis systems and methods
    Patent number: 7988839
    Abstract: An embodiment of the invention is directed to a capillary electrophoresis apparatus comprising a plurality of separation micro-channels. A sample loading channel communicates with each of the plurality of separation channels. A driver circuit comprising a plurality of electrodes is configured to induce an electric field across each of the plurality of separation channels sufficient to cause analytes in the samples to migrate along each of the channels. The system further comprises a plurality of detectors configured to detect the analytes.
    Type: Grant
    Filed: September 20, 2006
    Date of Patent: August 2, 2011
    Assignee: University of Louisville Research Foundation, Inc.
    Inventors: Rathissh Dorairaj, Robert S. Keynton, Thomas J. Roussel, Mark M. Crain, Douglas J. Jackson, Kevin M. Walsh, John F. Naber, Richard P. Baldwin, Danielle B. Franco

  • Capillary electrophoresis-electrochemical detection microchip device and supporting circuits
    Patent number: 7344628
    Abstract: The present invention is a capillary electrophoresis device, comprising a substrate; a first channel in the substrate, and having a buffer arm and a detection arm; a second channel in the substrate intersecting the first channel, and having a sample arm and a waste arm; a buffer reservoir in fluid communication with the buffer arm; a waste reservoir in fluid communication with the waste arm; a sample reservoir in fluid communication with the sample arm; and a detection reservoir in fluid communication with the detection arm. The detection arm and the buffer arm are of substantially equal length.
