Description
Summary:In this study, a novel electrochemical luminescence based on ternary nanocomposite as CuS/CQDs/g-C 3 N 4 NS was demonstrated for accurate determination of imidacloprid. The synthesized nanocomposite was prepared by a simple microwave path. This composite presented superior proficiency in the enhancement of the ECL signal. Carbon quantum dots and copper sulfide nanostructures have a good cooperative effect on the ECL signal enhancement of the graphitized carbon nitride nanosheets. Also, boron nitride quantum dots were introduced as a new and effective co-reactant in the negative potential window for the first time. Luminophore signal intensity is significantly increased in the presence of appropriate amount of boron nitride quantum dots. The ultrasensitive electrochemiluminescence probe was truly applied for analysis of imidacloprid. For this end, the broad linear dynamic range and ultralow limit of detection from 2.0 × 10 –15 to 5.0 × 10 –9  M and 3.0 × 10 –16  M were obtained, respectively. Also, the fabricated insecticide sensor exhibited good repeatability for 20 consecutive optical signals with a relative standard deviation of about 1.9%. Owing to supreme properties towards the accurate analysis of imidacloprid, the developed ECL sensor was implemented as a novel applicable probe for monitoring of imidacloprid. Graphic abstract
