The particles were prepared by copolymerization of the methacryloyl groups on the surface of silica particles modified with 3-methacryloxypropyl trimethoxysilane a functional monomer and a cross-linking agent. The imprinted particles exhibit larger binding capacity, faster binding kinetics, and higher recognition selectivity for CPF. Combined with highly sensitive chemiluminescence assay, the method was applied to the determination of CPF with a detection limit of 0.92nM which is about 2 orders of magnitude lower than that by conventional CL method. The method also displays repeatability for more than 200 times. Figure Schematic illustration of a surface molecular imprinting strategy for synthesizing core-shell particles with CPF-imprinted shells and the CL kinetics curves of MIP-based CL method for the determination of chlorpyrifos.
