Abstract
Provided is a method of sensing biomolecules using a bioFET, the method including: forming a layer including Au on a gate of the bioFET; forming a probe immobilized on a substrate separated from the gate by a predetermined distance, and a biomolecule having a thiol group (—SH) which is incompletely bonded to the probe; reacting the probe with a sample including a target molecule; and measuring a current flowing in a channel region between a source and a drain of the bioFET.
