英文摘要: The co-precipitation and thermal decomposition method will be used for controllable synthesis of magnetic nanomaterial in this project. Through modification techniques, the surface functional group on the magnetic nanoparticles will be conjugated with antibody and biotin, respectively. The parameters for synthesis of magnetic nanoparticles, labeling conditions will be optimized, and high performance magnetic nanoprobe will be obtained. Based on the prepared nanoprobe, the detection will be performed in immunoassay formats in microplate, including antigen coating, washing steps, etc., through magnetic nanoparticles catalyzed tetramethylbenzidine chromogenic reaction, and we will finally achieve rapid, highly sensitive detection of plasticizing agent. At the same time, the developed nanoprobe can also be used as magnetic resonance nanoprobe for magnetic resonance relaxation detection. The developed magnetic nanoparticle sensor detection will be compared with horseradish peroxidase, and the advantages of the method, repeatability, stability will be evaluated.
