  • Redox polymers for use in electrochemical-based sensors
    Patent number: 7592151
    Abstract: A redox polymer for use in an electrochemical-based sensor includes a hydrophobic polymer backbone (e.g., a hydrophobic poly(methyl methacrylate) polymer backbone) and at least one hydrophilic polymer arm (such as a hydrophilic oligo(N-vinylpyrrolidinone) polymer arm) attached to the hydrophobic polymer backbone. The redox polymer also includes a plurality of redox mediators (e.g., ferrocene-based redox mediators) attached to the at least one hydrophilic polymer arm.
    Type: Grant
    Filed: October 19, 2007
    Date of Patent: September 22, 2009
    Assignee: Lifescan, Inc.
    Inventors: Zuifang Liu, James Jain Rodgers, Geoffrey Ulue
