A Novel CdSe/ZnS Quantum Dots Fluorescence Assay Based on Molecularly Imprinted Sensitive Membranes for Determination of Triazophos Residues in Cabbage and Apple.

ABSTRACT: In the present study we have developed a direct competitive CdSe/ZnS quantum dot (QD) fluorescence assay based on micro-array-imprinted membranes for the determination of triazophos in cabbage and apple. The imprinted membranes were directly synthesized on the surface of a 96-well plate by thermal polymerization using triadimefon as the dummy template. Under optimal conditions, the assay showed an excellent linear response over the concentration ranges of 0.1-10,000 μg L^-1 with a good coefficient of determination (R ²= 0.982). The sensitivity (IC₅₀) and limit of detection (LOD, expressed as IC₁₅) of the developed assay were 3.63 mg L^-1 and 0.31 μg L^-1, respectively. The applicability of the developed approach was test
