  A bioanode for glucose based biofuel cell have been fabricated by combining glucose oxidase and highly ordered Palladium (Pd) nanowire array electrode. The Pd nanowires were 5.57 μm in length and 64.28 nm in diameter. The hydrogel composite modified Pd nanowire array bioanodes were characterized with cyclic voltammetry in the presence of different scan rates and different substrate concentrations under physiological conditions. The electrochemical measurements showed a linear amperometric response in the range of 1 mM to 13 mM. In addition, surface and structural characterization were performed by scanning electron microscopy leading to the conclusion that the Pd nanowires are highly ordered and vertically aligned and thereby promotes the number of electroactive sites for the catalysis of the oxidation of glucose. The combination of glucose oxidase and Pd nanowire arrays revealed.. Read More»
