新兴纳米材料在食品安全检测样品前处理中的应用
食品安全是全球公共卫生关注的重大问题, 食品中的多种污染物严重威胁着人类健康, 由于食品基质复杂且污染物含量低, 难以直接对目标污染物进行分析, 有效的样品前处理是痕量污染物分析必不可少的环节。近年来, 纳米材料的兴起促进了样品前处理技术的发展。本文全面综述了近3年(2018~2020)基于碳纳米材料、金属有机框架、共价有机框架、聚多巴胺衍生材料以及分子印迹聚合物等新兴纳米材料的固相萃取技术、磁性固相萃取技术、分散固相萃取技术、固相微萃取技术等样品前处理技术在食品样品污染物分析中的研究进展, 分析了基于以上纳米材料的食品样品前处理方法的优势和局限性, 并对该领域未来发展前景进行了展望。
Food safety has been a global public health concern. Numerous contaminants in food seriously threaten human health. Due to the complexity of food matrix and trace level of contaminants, it is difficult to directly analyze the target contaminants, so the effective food pretreatment approach is of great significance to analyze trace contaminants. Recently, development of nanomaterials has greatly promoted the innovation of food sample pretreatment methods. This review comprehensively summarized the progress of pretreatment methods including solid-phase extraction, solid-phase microextraction, dispersive solid-phase extraction, magnetic solid phase extraction for food safety screening based on the emerging nanomaterials including carbon nanomaterials, metal organic frameworks, covalent organic frameworks, polydopamine-derived materials and molecularly imprinted polymers (period 2018-2020), outlined their advantages and limitations, and discussed the future development prospects and challenges in this ?eld as well.
