A biosensor bound by EPDM solved in toluene has been newly designed and a study of its electrochemical characteristics was carried out. Enzyme source was ground tissue of cabbage root. Volatilization of the solvent made the electrode material possess a mechanical robustness and a speedy signal appearance. And it showed electrochemically irreversible behaviors and a powerful catalytic power(detection limit = 5.0 x 10-5 M, S/N=2). The double reciprocal plot of signal current and substrate concentration was ideally linear and the symmetry factor and exchange current density of the electrode used in this work were 0.16 and 3.61 x 10-5 Acm-2 respectively.
