中文摘要：
磁性固相萃取是当前对复杂样品中痕量目标物进行有效分离富集的热门技术，功能化磁性微纳米粒子是该技术应用中的关键材料。本文综述了各种已报道的功能化磁性微纳米材料，总结了包括表面嫁接有机小分子、表面包覆碳或无机氧化物、表面嫁接或包覆聚合物、载体表面或孔道内负载磁性纳米粒子、载体骨架内掺入磁性纳米粒子、物理共混法制备磁性功能材料在内的6种功能化方法，并对功能化磁性微纳米材料在食物样品前处理中的应用进行了简要评述。
英文摘要：
Magnetic solid phase extraction technique,based on functional magnetic materials, is currently a hot topic in the separation and analysis of complex samples. This paper reviews the reported methods for the functionalization of magnetic micro-/nano-materials,such as sur-face grafting organic groups,coating carbon or inorganic oxide,grafting or coating polymer, being loaded to the surface or pores of supports,being introduced into the skeleton of sup-ports,and physically co-mixing methods. Moreover,we briefly introduce the applications of the functional magnetic micro-/nano-materials in pretreatment for food samples.
