Abstract

A ferrocene-mediated glucose biosensor removing interference of ascorbic acid and uric acid was developed by coating of ferrocene, glutin and cellulose acetate on screen-printed gold electrode surface. The results show that it can detect glucose sensitively in the presence of uric acid and ascorbic acid, and also suppress the leakage velocity of ferrocene. Compared to the currents of the pretreated electrode, it decreases the current of uric acid and ascorbic acid by 99.4% and 98.8% at 400 mV, respectively, with a dynamic range of 0-30 mM for glucose, sensitivity of 30.73 nA/mM, response time of 10 s, and correlation coefficient of 0.9988.
