  • Method for surface modification to create regions resistant to adsorption of biomolecules
    Patent number: 5965305
    Abstract: Irradiating, with ultraviolet light, surfaces which contain thiol groups, epoxy groups, or vicinal diol groups, results in surfaces which exhibit a reduced adsorption of biomolecules. In the case of surfaces having thiol groups such irradiation also results in a reduced capacity for the bonding of heterobifunctional crosslinking reagents. Such irradiation may be carried out in a patternwise fashion to obtain patterned surfaces.
    Type: Grant
    Filed: January 3, 1995
    Date of Patent: October 12, 1999
    Assignees: The United States of America as represented by the Secretary of the Navy, GEO-Centers, Inc.
    Inventors: Frances S. Ligler, Suresh Bhatia, Lisa C. Shriver-Lake, Jacque Georger, Jeff Calvert, Charles Dulcey
