In this paper, we report a novel glucose biosensor based on composite of An nanoparticles (NPs)-conductive polyaniline (PAM) nanofibers. Immobilized with glucose oxidase (GOx) and Nafion on the surface of nanocomposite, a sensitive and selective biosensor for glucose was successfully developed by electrochemical oxidation of H2O2. The glucose biosensor shows a linear calibration curve over the range from 1.0 x 10(-6) to 8.0 x 10(-4) mol/L, with a slope and detection limit (S/N = 3) of 2.3 mA/M and 5.0 x 10(-7) M, respectively. In addition, the glucose biosensor system indicates excellent reproducibility (less than 5% R,S.D.) and good operational stability (over 2 weeks). (c) 2005 Elsevier B.V. All rights reserved.
