I. Willner et al., DEVELOPMENT OF NOVEL BIOSENSOR ENZYME ELECTRODES - GLUCOSE-OXIDASE MULTILAYER ARRAYS IMMOBILIZED ONTO SELF-ASSEMBLED MONOLAYERS ELECTRODES, Advanced materials, 5(12), 1993, pp. 912-915
Amperometric biosensors under development are based on electron transf
er communication between enzyme redox sites and electrodes. These requ
ire 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 f
unctionalized thiols on gold electrodes. The protein array supports el
ectrical communication with the electrode, and the resulting assembly
can be used as a glucose biosensor.
