Fluorescence Resonance Energy Transfer (FRET)- Based Sensor for Detection of Foodborne Pathogenic Bacteria: A Review

ABSTRACT
Sensitive and rapid determination of foodborne pathogenic bacteria is of practical importance for
the control and prevention of foodborne illnesses. Nowadays, with the prosperous development
of fluorescence assays, fluorescence resonance energy transfer (FRET)-derived diagnostic strategies
are extensively employed in quantitative analysis of different pathogenic bacteria in food-related
matrices, which displays a rapid, simple, stable, reliable, cost-effective, selective, sensitive, and realtime way. Considering the extensive efforts that have been made in this field so far, we here discuss the up-to-date developments of FRET-based diagnostic approaches for the determination of
key foodborne pathogens like Staphylococcus aureus, Escherichia coli, Vibrio parahaemolyticus,
Salmonella spp., Campylobacter spp., and Bacillus cereus in complex food-related matrices.
Moreover, the principle of this technology, the choosing standards of acceptor-donor pairs, and
the fluorescence properties are also profiled. Finally, the current prospects and challenges in this
field are also put forward
