Kathleen J. Doane 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).

  • Detection and amplification of ligands
    Patent number: 7927827
    Abstract: A system for the detection of ligands comprising at least one receptor and an amplification mechanism coupled to the receptor wherein an amplified signal is produced as a result of receptor binding a ligand. Examples of suitable amplification mechanisms include antibody-embedded liquid crystalline materials; use of alpha-2-macroglobulin to encage an enzyme, whereby the enzyme is separated from its substrate by an receptor; and a receptor engineered to inhibit the active of site of an enzyme only in the absence of a ligand. Also provided are methods for the automatic detection of ligands.
    Type: Grant
    Filed: May 21, 2007
    Date of Patent: April 19, 2011
    Assignee: Kent State University
    Inventors: Gary D. Niehaus, Christopher J. Woolverton, Kathleen J. Doane, Steven P. Schmidt, Steven A. Signs
