Summary: Graphdiyne (GDY) has been widely applied in electrochemical sensing due to its large conjugation system, porous structure, and high structure defects. In this study, conductive MWCNTs were added to enhance the sensing effect of GDY. By using polydopamine (PDA) as a connecting bridge, a stable composite material GDY@PDA/MWCNTs-NH2 was formed and used as an electrochemical sensor for benomyl (Ben) detection. The sensor exhibited a wide linear range, low detection limit, high stability, repeatability, reproducibility, and selectivity, making it suitable for detecting Ben in apple and cucumber samples.
