Patents by Inventor Angela M. Zapata

Angela M. Zapata 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).

  • Apparatus and systems for processing samples for analysis via ion mobility spectrometry
    Patent number: 7968842
    Abstract: The invention provides an interface assembly for delivering an ionized analyte from an ionization apparatus into an ion mobility spectrometer. This allows analysis of biological and non-biological samples, even non-volatile solids, via differential mobility spectrometry, without fragmentation of molecules. The invention also provides portable sample analysis systems that operate at ambient pressure. Systems of the invention may be used for high molecular weight species detection, for example, drinking water contaminants, pathogenic biological agents, bio-organic substances, non-biological material, peptides, proteins, oligonucleotides, polymers, bacteria, and hydrocarbons.
    Type: Grant
    Filed: May 16, 2008
    Date of Patent: June 28, 2011
    Assignee: The Charles Stark Draper Laboratory, Inc.
    Inventors: Angela M. Zapata, Ernest S. Kim, Priya Agrawal, Melissa D. Krebs, Cristina E. Davis

  • DEVICES, SYSTEMS, AND METHODS FOR MEASURING GLUCOSE
    Publication number: 20090014340
    Abstract: Systems and methods for detecting glucose in a sample using, for example, a regenerable sensor are described. The sensor may, for example, include boronic acid to detect with great sensitivity and at a low cost the glucose in the sample.
