Abstract
New reloadable biosensors were developed by affinity binding of glucoenzymes peroxidase and glucose oxidase on pF-sensitive field-effect transistors (Si/SiO2/Si3N4/LaF3 layers). The basic measuring principle of these ion sensitive field-effect transistors is the current change depending on the concentration of F- ions. The immobilized glucoenzymes can be removed from the enzymatically inactive Concanavalin A basic membrane and fresh enzymes can be bound again. The principle of this reloadable biosensor is described in detail. Additionally, the biosensor was successfully integrated in a flow-injection analysis system for measuring glucose during a cultivation process.
