  • Antimicrobial coating comprising chalcogenide nano-particles capped by chitosan
    Patent number: 11825847
    Abstract: Disclosed herein are methods of making pure chalcogenide (e.g., selenium, tellurium, or selenium/tellurium) nanoparticles by irradiating chalcogenide pellets by nano-second laser ablation using chitosan as a capping agent to form chitosan chalcogenide nanoparticles (CS-CgNPs). CS-CgNPs and methods of using such particles are also disclosed herein, such as antimicrobials and antimicrobial coatings effective against biofilms.
    Type: Grant
    Filed: August 2, 2021
    Date of Patent: November 28, 2023
    Assignee: Board of Regents, The University of Texas System
    Inventors: Kelly Nash, Gregory Guisbiers, Humberto Herman Lara Villegas
