英文摘要： Most organophosphorus（OP） pesticides are widely used in controlling insects in agriculture across the world, but they also leading to long-term accumulation in ecosystems including humans. Therefore, there is a great demand to develop a fast, sensitive,and reliable assay of OP pesticide residues to improve food safety and to protect the ecosystem.The development of nanotechnology provides new opportunities for the measurement of OP pesticide residues. In this issue, we attempt to combine the advantages of dual emission fluorescent nanoparticles and molecular imprint materials and prepare 3-5 types of new fluorescent nanosensor composed of dual emission nanomaterials and molecular imprint materials, and develop new visual detection method for OP pesticides residues. Investigate the feasibility of this new nanosensor for the detection of OP pesticides residues in complicated samples. The meaning of this item is combine the accuracy, sensitivity and visual under Uv irridiation of dual emission nanomaterials and the high selectivity of molecular imprint materials, developed new method for the visual detection of OP residual in complex samples, it is meaningful for increasing the detection ability for pesticide residual, improve food safety and to protect the ecosystem, extended the application of nanomaterials in po
