Patents by Inventor Patricia M. Biessener

Patricia M. Biessener 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).

  • Microstructured polymeric substrate
    Patent number: 7105809
    Abstract: Methods and apparatuses for the high-energy desorption/ionization of various compositions are disclosed. The methods and apparatuses of the invention generally utilize structured substrates, such as micro- and nano-structured films, optionally in combination with one or more surface coatings, to provide enhanced desorption of analytes. Such enhanced desorption is particularly useful in fields of analysis such as mass spectroscopy which use laser desorption of the substrate.
    Type: Grant
    Filed: November 18, 2002
    Date of Patent: September 12, 2006
    Assignee: 3M Innovative Properties Company
    Inventors: Kenneth B. Wood, Raymond P. Johnston, Patricia M. Biessener
