Salmonella sensor, preparation method and detection method of salmonella concentration

Abstract

The invention discloses a salmonella sensor, a preparation method and a detection method of salmonella concentration. The salmonella sensor comprises an electrolytic tank, an electrolyte which is arranged in the electrolytic tank, an organic electrochemical transistor which is arranged in the electrolytic tank and a gate electrode which is arranged in the electrolytic tank, wherein the organic electrochemical transistor comprises a substrate, a source electrode and a drain electrode which are arranged on the substrate and an organic semiconductor film layer which coats the substrate and connects the source electrode and the drain electrode; a photoelectric active semiconductor material modifies the gate electrode as a sensitive function layer of the sensor; and an antibody combined with salmonella is fixed on the gate electrode modified by the photoelectric active semiconductor material. The salmonella sensor disclosed by the invention has extremely high sensitivity and extremely low detection limit, and is simple and easy to microminiaturize. The detection method of salmonella concentration based on the salmonella sensor can realize fast and simple high-sensitivity salmonella concentration detection.
