  • Patent number: 12196748
    Abstract: The present invention provides for a composition for ionizing a target comprising: a substrate comprising a plurality of nanoparticles bound to a surface of the substrate, which allows one to directly extract undesired contaminants during passive sample drying without require manual interventions, such as washing and vortexing.
    Type: Grant
    Filed: July 22, 2019
    Date of Patent: January 14, 2025
    Assignees: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA, NATIONAL TECHNOLOGY & ENGINEERING SOLUTIONS OF SANDIA, LLC
    Inventors: Todd A. Duncombe, Trent R. Northen
  • Patent number: 10852272
    Abstract: Provided are devices that include a polymeric separation medium configured to immobilize one or more constituents of interest in the polymeric separation medium and have an increased pore size upon application of an applied stimulus. Systems including the devices, as well as methods of using the devices, are also provided. Embodiments of the present disclosure find use in a variety of different applications, including detecting whether an analyte is present in a fluid sample.
    Type: Grant
