The method is implemented by assembling a sodium 3,3?-dithiodipropane sulfonate (SPS) membrane on a surface of Au membrane layer of an Au electrode and using an extended gate of field effect transistor (FET) and in-situ signal amplification of the FET to detect L-cystine sensitively. The polyanion of the SPS membrane adsorbs and binds a positively charged target L-cystine through electrostatic interaction, thus forming an electric double layer structure to generate a membrane potential identifying a monovalent organic ammonium ion. The sensor includes the FET, wherein a gate-extended gold electrode is arranged on the FET, and the SPS membrane is assembled on the surface of the Au membrane layer of the gate-extended gold electrode.
