Abstract

-based sensor demonstrates an excellent linear relationship between the mass concentration of profenofos (lgC) and the inhibition rate (Inh %) within the range of 1∼2000 µg/L with a detection limit of 0.137 µg/L. Furthermore, this biosensor presents excellent reproducibility, anti-interference, and stability for the detection of profenofos in real samples. This study paves an avenue to construct a cluster-based detection platform with high performance in electrochemical sensing, facilitating the practical application of metal nanoclusters in pesticide detection.
