A Glucose Biosensor Based on Immobilization of Glucose Oxidase on Platinum Nanoparticle Doped Santa Barbara Amorphous Material-15

Abstract

A novel electrochemical glucose biosensor was prepared by combining platinum nanoparticle doped Santa Barbara Amorphous Material 15 with glucose oxidase. The resulting material demonstrated high stability and reactivity for catalyzing glucose electrolytic oxidation, primarily due to the high surface area of these catalysts. This glucose biosensor was capable of interference-free determination of glucose with a linear dynamic range from 0.03 to 12.0 mmol L⁻¹. In addition, it has the advantages of simple preparation and good stability. The reported method is promising for the determination of glucose in human serum.
