Abstract
Provided is a method of detecting the presence of a target bio-molecule or a concentration of the bio-molecule using a field effect transistor. The method includes: contacting a first sample having a first target bio-molecule with a reference electrode of a field effect transistor; measuring a first electric signal change of the field effect transistor; contacting a second sample with a sensing surface of the same field effect transistor; measuring a second electric signal change of the field effect transistor; and comparing the first electric signal with the second electric signal.
