Abstract
A new terpolymer was synthesized by grafting 4-vinylpyridine and acrylamide on the backbone of poly(vinyl alcohol). A glucose biosensor based on immobilization of glucose oxidase in the terpolymer gel is described. The enzyme electrode responds to glucose in 7∼ 10 s and gives a current density of 480 nA/mm2 for 1 mmol/L glucose at 0. 65 V (vs. Ag/AgCl). A linear calibration curve is obtained over the range 1×10-5∼5. 0×10-3 mol/L and the enzyme electrode retains 85% of initial response after a use period of two months.
