Peter J. S. Smith 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).

  • Self-referencing enzyme-based microsensor and method of use
    Patent number: 6802957
    Abstract: A micron-scale self-referencing microsensor is disclosed which uses an enzyme-based electrode to measure the flux of an electrochemically inactive analyte such as glucose. The electrode oscillates between at least two positions. In the presence of the analyte, the enzyme generates a species detectable by the electrode.
    Type: Grant
    Filed: September 28, 2001
    Date of Patent: October 12, 2004
    Assignee: Marine Biological Laboratory
    Inventors: Sung-Kw n Jung, Richard H. Sanger, Peter J. S. Smith, John R. Pepperell

  • Polarographic self-referencing probe and method for using
    Patent number: 5968340
    Abstract: A polarographic self-referencing probe uses an electrode that is oscillated between two positions. Depending on the electrode used and the voltage applied, the probe can be used to measure oxygen, nitric oxide, or other molecules or compounds.
