| 摘 要： | 食源性致病菌是影响食品安全的主要因素之一。食品中污染的致病菌数量通常较少，加上其基质复杂，常规分析方法常无法直接对致病菌进行高灵敏、高特异的检测。经过生物学修饰和功能化的磁性纳米材料，可特异性地识别食品基质中少量的致病菌，并通过磁场对靶细菌进行快速及高特异性的选择性分离，实现了食品样品中少量致病菌的特异性分离富集，达到了后续分析检测的纯度和数量。本文综述了磁性纳米材料在食源性致病菌分离富集中的研究进展。 |

| Abstract: | Foodborne pathogenic bacteria are one of the major factors that influences food safety. Pathogens in limited numbers are not easy to directly detect with high sensitivity and specificity in food matrices via routine analytical methods. Magnetic nanomaterials with biological modification and functionalization can specifically recognize foodborne pathogenic bacteria in food samples. Target bacteria can be separated selectively with rapidity and high specificity by a magnetic field, which realizes the specific separation and enrichment of low numbers of pathogens in food samples, providing enriched pathogens with higher purity and quantity for further study. This paper reviews recent progress in applying magnetic nanomaterials for the separation and enrichment of foodborne pathogens. |
