In the present study, a novel AgO x /BiPO4 sensor was successfully prepared and used for detecting trans-resveratrol. Prepared samples were characterized using methods including X-ray diffraction, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy. The results demonstrate that the AgO x /BiPO4 is composed of AgO, Ag2O, and BiPO4. In addition, a cyclic voltammetry method was used to measure resveratrol concentration using the electrochemical sensor based on AgO x /BiPO4. AgO x /BiPO4 presents a well-defined voltammetric peak at approximately +460 mV versus Ag/AgCl in phosphate-buffered saline solution. In addition, the sensor exhibits a detection limit of 1.0×10−7 M, and the wide dynamic concentration ranges from 2.0×10−7 to 12.5×10−6 M. Stability and interference tests were performed for 20 days. A possible mechanism for AgO x /BiPO4 detection of trans-resveratrol detection is proposed.
