The invention provides an electrochemical extended-gate transistor (EET) system. The system includes: a field effect transistor (FET), which has a gate electrode, a source electrode, and a drain electrode. A potentiometer having a working electrode, a counter electrode, and a reference electrode; wherein the working electrode is coupled to a detection area, and the pair of electrodes is coupled to the gate; wherein the detection area, the gate, and the reference The electrode is placed in an ionic fluid; wherein the potentiostat is configured to electrochemically generate a redox reaction in the ionic fluid to detect the target. A method for detecting targets is used in this system. |
