Abstract
A bio sensor using a FET element and an extended gate, and an operating method thereof are disclosed. A biosensor using a field effect transistor (FET) device and an extended gate electrode according to the present invention is characterized by comprising: an extended gate electrode connected to the FET element; a sensing electrode made of the same material as the extended gate electrode and on which a receptor antibody selectively recognizing a target molecule is fixed; and a reference electrode that maintains a constant potential and is selectively connected to the sensing electrode.
