A penicillin G biosensor, systems comprising the same, and measurement using the systems. The penicillin G biosensor has an extended gate field effect transistor (EGFET) structure and comprises a metal oxide semiconductor field effect transistor (MOSFET) on a semiconductor substrate, a sensing unit comprising a substrate, a tin oxide film on the substrate, and a penicillin G acylase film immobilized on the tin oxide film, and a conductive wire connecting the MOSFET and the sensing unit.
