  • Title: Improved selectivity and stability of glucose biosensor based on in situ electropolymerized polyaniline-polyacrylonitrile composite film.
    Author: Xue H, Shen Z, Li C.
    Journal: Biosens Bioelectron; 2005 May 15; 20(11):2330-4. PubMed ID: 15797335.
    Abstract:
    A new type of in situ electropolymerization method was used for electrochemical biosensor design. The biologic film was prepared by in situ electropolymerization of aniline into microporous polyacrylonitrile-coated platinum electrode in the presence of glucose oxidase. The novel glucose biosensor exhibited good selectivity, sensitivity and stability, which showed no apparent loss of activity after 100 consecutive measurements and intermittent usage for 100 days with storage in a phosphate buffer at 4 degrees C. Blood glucose determinations agreed well with standard hospital laboratory analysis. The construction and operational parameters of the biosensor were also optimized.
