The electrochemical characteristics of the modified SPCEs were analyzed by cyclic voltammetry, chronopotentiometry, electrochemical impedance spectroscopy and chronoamperometry. Results show that the response current of glucose biosensor could be enhanced at PPy-Au NPs modified electrode because of uniform distribution of ferricyanide and larger electroactive area on the SPCEs. The sensitivity of the resulting biosensor for glucose was ca. 0.563 μA/mM with a wide linearity up to 600 mg/dl and the lower detection limit of about 0.52 mM.
