Abstract
In this study, an electrochemiluminescence detection system for the sensitive detection of carbaryl was constructed based on the dual identification of Eu@MOF253, which has a recognition effect on carbaryl, and the electrochemiluminescence system of Ru(bpy)32+/S2O82-, which can react with carbaryl in a redox reaction. This method not only overcame the weakness of the electrochemiluminescence instability of the Ru(bpy)32+/S2O82- system but also changed the sensitivity of the sensing detection system to the target by adjusting the concentration of Ru(bpy)32+ and then proposed a detection strategy with a controllable detection range. After analyzing the electrochemiluminescence signal change mechanism of this system and optimizing the detection conditions, it was concluded that the strategy has good linear detection of carbaryl in the range of 1-1000 and 0.02-0.3 μg L-1, and the detection limits were 0.058 and 0.014 μg L-1. Finally, the strategy was also successfully applied to the detection of actual samples.

Abstract
A hapten-protein conjugate with copper nanoparticles (Hap-Car-BSA@CuNPs) was first synthesized in the present work for the determination of carbaryl. The copper nanoparticles (CuNPs) of the conjugate were used as electrochemical labels in the direct solid-phase competitive determination of carbaryl residues in flour from different crops. The signal was read by linear sweep anodic stripping voltammetry (LSASV) of copper (through the electrochemical stripping of accumulated elemental copper) on a gold-graphite electrode (GGE). To form a recognition receptor layer of monoclonal antibodies against the carbaryl on the surface of the GGE, 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC) and 1-hydroxy-2,5-pyrrolidinedione (NHS) were used as the best covalent cross-linkers. The concentrations of the antibodies and the Hap-Car-BSA@CuNPs conjugate were optimized for carbaryl detection by the electrochemical immunosensor. The electrochemical immunosensor can be used for highly sensitive determination of carbaryl residues in flour samples in the concentration range 0.8-32.3 μg·kg-1, with a limit of detection 0.08 μg·kg-1. The present work paves the path for a novel method for monitoring carbaryl in other food products, drinks, and soil samples.
