Enzyme-Based Biosensors

Enzyme-based chemical biosensors are based upon biological recognition. The detection typically relies on an enzyme system that catalytically transforms analytes into products that can be oxidized or reduced at a working electrode, maintained at a specific potential. First enzyme-based potentiometric biosensor in which urease enzyme was immobilized on an ammonia electrode for the perception of urea.
