Doug Hansmann 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).

  • Devices for cell assays
    Patent number: 9968935
    Abstract: The present invention relates to the field of molecular diagnostics. In particular, the present invention provided improved substrates and methods of using liquid crystals and other biophotonically based assays for quantitating the amount of an analyte in a sample. The present invention also provides materials and methods for detecting non-specific binding of an analyte to a substrate by using a liquid crystal or other biophotonically based assay formats.
    Type: Grant
    Filed: August 20, 2008
    Date of Patent: May 15, 2018
    Assignee: Platypus Technologies, LLC
    Inventors: Nicholas Abbott, Christopher Murphy, Barbara Israel, Josh Sotos, Doug Hansmann, Renee Herber, Joseph Burkholder, Keren Hulkower, Michael Bonds
  • Liquid crystal based analyte detection
    Patent number: 9816147
    Abstract: The present invention relates to the field of detection of viruses, and in particular to detection of viruses using a liquid crystal assay format. In the present invention, virus binding in a detection region is identified by changes in liquid crystal orientation caused by virus binding independent orientation caused by any topography associated with the detection region.
