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.

Key words: magnetic nanomaterials, foodborne pathogenic bacteria, separation, enrichment
