摘要：

A new method for the rapid detection of neonicotinoid pesticides based on metal halide perovskite quantum dot fluorescent probes was constructed by taking neonicotinoid pesticides as the target and combining fluorescence sensing strategies. The linear detection range of the method was 0-20 mg/L，the linear correlation coefficient was 0. 993 9，the detection limit was 0. 17 mg/kg. The recovery rate of clothianidin spiked in banana and radish samples was 79. 3%-115. 4%，and the relative standard deviation was less than 9. 4%. This method has high sensitivity，high selectivity and applicability，and provides an effective detection technology for the risk prevention and control of clothianidin in agricultural products and food. The interaction between clothianidin and perovskite quantum dots was studied. The results showed that the interaction between perovskite quantum dots and clothianidin was a dynamic process，and the fluorescence quenching of clothianidin to perovskite quantum dots was static quenching of new complexes formed by hydrogen bonds or van der Waals forces. Its content can be used as the technical basis of other spectral analysis methods，and its analysis and detection results can provide valuable suggestions for the safety supervision of fruits and vegetables. © 2024 Editorial Office of Chinese Optics.
