Amperometric Biosensors Based on 3-Dimensional Hydrogel-Forming Epoxy Networks
Abstract
Proteins and glycoproteins of enzymes behave with respect to electron transport, but not ion transport, as good electrical insulators. We have shown that these insulators can be made sufficiently electron conducting to allow the flow of a current between reaction centers of redox enzymes and electrodes equaling or exceeding the current associated with the turnover of the enzymes. In order for such a current to flow it is necessary to introduce into the enzyme proteins of glycoproteins fast electron relaying centers, so as to reduce the electron transfer distances.
