摘要
A novel enzymeless glucose sensor of poly (sulfosalicylic acid) film modified nickel disk-microelectrode based on glucose electrochemical oxidation directly in 0.01 mol dm(-3) NaOH has been fabricated. It shows excellent electrocatalytic activities towards glucose oxidation at a low positive potential of 0.49V (vs. Ag/AgCl). The calibration curve is linear in the glucose concentration range of 6.0 x 10(-6) to 1.0 x 10(-3) mol dm(-3) with a detection limit 9 x 10(-7) mol dm(-3) (S/N = 3) and sensitivity 3.8mA mu M(-1) cm(-2). The presented glucose sensor is selective, sensitive, and rapid in response time. It had been used to direct determination of glucose in serum.
