Alkaloid sensor, systems comprising the same, and measurement using the systems

摘要

An alkaloid sensor, systems comprising the same, and measurement using the systems. The alkaloid sensor 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 alkaloid acylase film immobilized on the tin oxide film, and a conductive wire connecting the MOSFET and the sensing unit.
