磁性分子印迹聚合物最新进展

摘要

Magnetic nanoparticles (MNPs) because of their attractive properties such as small size, high surface-to-volume ratio, high magnetic susceptibility and effective ability for binding have been used in various fields. MNPs can be easily and effectively separated with an external magnetic field without any additional centrifugation or filtration procedures, and surface molecular imprinted polymers (MIPs) have high selective and effective recognition for template molecule. The combination of the two technologies has become a research hot spot for solid phase extraction. This review focused on the preparations and applications in the field of magnetic molecular imprinted polymer in recent years.%磁性纳米颗粒因其具有粒径小、比表面积大、磁化率高、键合力强等优点而被广泛的应用到多种领域。磁性纳米颗粒仅在外加磁场作用下就可实现高效分离，无需离心和过滤，而表面分子印迹聚合物具有高度识别特性，两种技术的结合成为近期分子印迹聚合物应用到固相萃取中的研究热点。文章从制备和应用的角度对近年来磁性分子印迹聚合物的研究进展做了简要综述。
