英文摘要	This paper reports the preparation and properties of biosenor using conducting composite material consisted of ethyl cellulose and acetylene black. The final biosensor was constructed by applying a mixture containing 0.010 g ethyl cellulose, 0.004 g acetylene black, a little paraffin wax and 0.2 mg glucose oxidase (23000 units/g solid, E. C. 1. 1. 3. 4, Sigma Chemical Co.) on a platinum electrode (3 mm x 3 mm). Effect of various factors on the response current of the biosensor was discussed. The response current increases linearly with increasing glucose concentration under 11.5 mmol . dm(-3). Its activation energy is 40.3 kJ . mol(-1) in enzyme-catalyzed reaction. AFM shows that the surface of conducting polymer composite material-glucose oxidase electrode's presents uniform granular structure after paraffin wax being washed with cyclohexane, which is favorable for enzyme-catalyzed reaction.
