  • Nanoparticle-attached enzyme cascades for accelerated multistep biocatalysis
    Patent number: 11512305
    Abstract: A nanoparticle (for example, quantum dot) serves as a substrate for immobilizing enzymes involved in consecutive reactions as a cascade. This results in a significant increase in the rate of catalysis as well as final product yield compared to non-immobilized enzymes.
    Type: Grant
    Filed: December 13, 2017
    Date of Patent: November 29, 2022
    Assignee: The Government of the United States of America, as represented by the Secretary of the Navy
