  • Patent number: 11052177
    Abstract: The invention provides compositions comprising a plurality of polymer layers for preventing or inhibiting microbial infections. Specifically, the invention provides a combination of a cationic polymer layer that resists adhesion of a microbe to its surface and an anionic polymer layer that releases a cationic anti-microbial agent in response to a change in pH or electrostatic balance.
    Type: Grant
    Filed: September 8, 2014
    Date of Patent: July 6, 2021
    Assignee: THE TRUSTEES OF THE UNIVERSITY OF PENNSYLVANIA
    Inventors: Hyun-Su Lee, David M. Eckmann, Russell Composto
  • Publication number: 20200236945
    Abstract: Antimicrobial compositions and methods for depositing or coating the antimicrobial or antibacterial compositions on a substrate to prevent microbial adhesion are provided. The antimicrobial composition may include a cationic polymer having a poly-allylamine backbone. A portion of the poly-allylamine backbone may be functionalized with at least one of a guanidine functional group and a biguanide functional group.
    Type: Application
    Filed: April 13, 2020
