Patents by Inventor Stephan Walters

Stephan Walters 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).

  • Biosensor electrode mediators for regeneration of cofactors
    Patent number: 8241485
    Abstract: The present invention is based on the discovery of NAD+ and NADP+ mediator compounds that do not bind irreversibly to thiol groups in the active sites of intracellular dehydrogenase enzymes. Such mediator compounds avoid a common mode of enzyme inhibition. The mediators can therefore increase the stability and reliability of the electrical response in amperometric electrodes constructed from NAD- or NADP-dependent enzymes.
    Type: Grant
    Filed: September 30, 2008
    Date of Patent: August 14, 2012
    Assignee: Abbott Laboratories
    Inventors: Nigel J. Forrow, Gurdial S. Sanghera, Jared L. Watkin, Stephan Walters
