Abstract

Enzyme electrodes for biosensors are discussed. Different methods to increase electron transfer between enzymes and electrodes are described. Results of encasing the enzymes in conducting polymers as well as in hydrogels are presented. The environment of the enzyme in the biosensor is compared to the natural environment of enzymes.
