Glucose Detection With a Commercial MOSFET Using a ZnO Nanowires Extended Gate
ZnO nanowires were grown on Ag wire with a diameter of similar to 250 mu m and used in an electrochemical sensor. The enzyme glucose oxidase (GOD) was immobilized on the ZnO nanowires, and the Ag wire was connected directly to the gate of a MOSFET. Upon exposure to glucose (1-100 mu M), the electrochemical response from the GOD induced a stable measurable voltage change on the gate leading to a st
