  • Method and compositions for manufacture of chemical sensors
    Patent number: 5326585
    Abstract: The method for making an optical fiber microsensor involves applying an uncured analyte sensing matrix to an optical fiber and crosslinking the sensing matrix in situ on the optical fiber to yield an ion permeable microsensor which can be used intravascularly to monitor pH, or partial pressures of oxygen or carbon dioxide in blood. The liquid form of the sensing matrix contains a crosslinking agent and a crosslinking inhibitor which can be removed by exposure to elevated temperatures to allow the sensing matrix to crosslink and cure as desired, in situ, on the surface of the optical fiber. A liquid crosslinking overcoat layer containing a crosslinking agent and a crosslinking inhibitor which can be removed by exposure to heat can also be applied over the cured sensing matrix.
    Type: Grant

    Date of Patent: July 5, 1994
    Assignee: Puritan-Bennett Corporation
