Abstract

Amperometric biosensors under development are based on electron transfer communication between enzyme redox sites and electrodes. These require well-organized networks of enzymes exhibiting long-range electron transfer properties. An enzyme electrode is described that consists of glucose oxidase networks organized on a self-assembled monolayer of functionalized thiols on gold electrodes. The protein array supports electrical communication with the electrode, and the resulting assembly can be used as a glucose biosensor.
