  • Method of increasing biocompatibility of medical device by generating nitric oxide
    Patent number: 8034384
    Abstract: A material includes a surface and a reactive agent that is located at the surface of the material, covalently attached to a backbone of the material, and/or located within the material. The reactive agent has nitrite reductase activity, nitrate reductase activity, and/or nitrosothiol reductase activity. The reactive agent also converts at least one of nitrites, nitrates and nitrosothiols to nitric oxide when in contact with blood. A reproducible nitrosothiol sensor is also disclosed.
