Abstract: A glucose electrode was constructed using a coba't tetraphenyl porphyrin modified elec-trode with response time of less than 4s. A linearship was obtained between the currentdecrease and the glucose concentration in the range of 0.05-0.8mmol/L. The activity of theglucose oxidase kepr unchanged for 3 months in icebax condition. The selectivity was satisfactory.

Key words: biosensor, modified electrode, glucose
