Abstract
Food safety has been a global public health concern. Humans are seriously endangered by numerous contaminants in foodstuffs. Owning to the complexity of food matrices, sample pretreatment is an essential step both in qualitative and quantitative analysis of trace contaminants. Thus, the effective food pretreatment method is of great importance. Recently, development of nanomaterials has greatly promoted the innovation of food sample pretreatment approach. For example, carbon-based materials, metal-organic frameworks, covalent-organic frameworks, polydopamine-derived materials, silica-based materials as well as molecularly imprinted polymers showed great prospects for food sample pretreatment. In this review, we comprehensively summarized the recent pretreatment methods based on the emerging nanomaterials for food safety screening (period 2016–2019), and outlined their advantages and limitations. In the end, we also discussed the future development prospects and challenges in this field. This review hopefully can stimulate interdisciplinary research at the intersection of the emerging nanomaterials and food sample pretreatment.
