Patents by Inventor Paul T. Shafer

Paul T. Shafer 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).

  • Multilayered bioelectronic sensors
    Patent number: 5571568
    Abstract: Bioelectronic sensors are provided employing a thin surfactant polymeric electrically conducting layer to which may be bound members of specific binding pairs. Binding of an analyte or a reagent to the specific binding pair member layer may change the electrical, optical, or structural properties of the layer for measurement of analyte. The change in the polymeric layer provides for a sensitive measurement.
    Type: Grant
    Filed: June 7, 1995
    Date of Patent: November 5, 1996
    Assignee: Biocircuits Corporation
    Inventors: Hans O. Ribi, Todd Guion, Paul T. Shafer
  • Analyte detection with multilayered bioelectronic conductivity sensors
    Patent number: 5491097
    Abstract: Methods are provided for the detection of an analyte in a sample using a bioelectronic sensor comprising a thin surfactant polymeric electrically conducting layer to which members of specific binding pairs are bound. Specific binding of analyte or analyte competitor to the bound specific binding pair member results in a change in the conductivity of the polymer. The resultant change in conductivity is related to the presence of analyte in the sample.
