摘要：

A potassium hexacyanoferrate(III) modified titanium dioxide electrode with immobilized glucose oxidase (GOD) was developed for measuring glucose. With this electrode, glucose concentration(1 x 10(-5) to 1 x 10(-3) M) could be determined accurately in the presence of ascorbic acid or uric acid. Glucose in human serum was determined after diluting the serum 10-fold with phosphate buffer of pH 5.5. The glucose concentrations of 70.5-72.7 mg dl(-1) were determined in good agreement with those usually found in human serum. (C) 2000 Elsevier Science S.A. All rights reserved.
