  • Patent number: 10794796
    Abstract: A novel, advanced polymeric swab is disclosed herein. The swabs have a surface texture that allows for independent motion between microscale regions, are reusable with no loss of accuracy or efficiency, and are fabricated from optoelectronically-active elements to minimize static charging during repeated use.
    Type: Grant
    Filed: September 18, 2015
    Date of Patent: October 6, 2020
    Assignee: Purdue Research Foundation
    Inventors: Stephen P Beaudoin, Bryan William Boudouris, Michelle Chaffee-Cipich, Aaron James Harrison, Stefan Lukow, Lizbeth Rostro, Caitlin Joy Schram, Kathryn Maureen Smith, Myles Calvin Thomas

  • Publication number: 20190011421
    Abstract: The present disclosure is directed to methods and systems for detecting a substance of interest. The methods and systems include contacting the substance of interest with a doped membrane, the doped membrane comprising at least one semi-permeable medium doped with at least one acid. The systems and methods further include desorbing the doped membrane to release the substance of interest, performing an analysis of the substance of interest, and detecting the substance of interest.
