Magnetic molecularly imprinted polymers (MMIPs) have superior advantages in sample pretreatment because of their high selectivity for target analytes and the fast and easy isolation from samples. To meet the demand of both good magnetic property and good extraction performance, MMIPs with various structures, from traditional core–shell structures to novel composite structures with a larger specific surface area and more accessible binding sites, are fabricated by different preparation technologies. Moreover, as the molecularly imprinted polymer (MIP) layers determine the affinity, selectivity, and saturated adsorption amount of MMIPs, the development and innovation of the MIP layer are attracting attention and are reviewed here. Many studies that used MMIPs as sorbents in dispersive solid-phase extraction of complex samples, including environmental, food, and biofluid samples, are summarized.

磁性分子印迹聚合物（MMIP）在样品预处理中具有优越的优势，因为它们对目标分析物具有很高的选择性，并且可以快速，轻松地从样品中分离出来。为了满足良好的磁性能和良好的提取性能的要求，通过不同的制备技术制造了具有各种结构的MMIP，从传统的核-壳结构到具有更大比表面积和更易接近的结合位点的新型复合结构。此外，由于分子印迹聚合物（MIP）层决定了MMIPs的亲和力，选择性和饱和吸附量，因此MIP层的发展和创新引起了人们的关注，并在此进行了综述。许多研究在复杂样品的分散固相萃取中使用MMIP作为吸附剂，
