Food safety is closely related to people's health and life safety

and foodborne pathogenic bacteria is the main factor affecting food safety.Diseases and deaths caused by foodborne pathogenic bacteria continue to threaten global public health.Therefore

development of rapid

accurate and sensitive detection methods for foodborne pathogenic bacteria is the key to prevent foodborne disease outbreaks and ensure food safety.Current conventional detection methods are time consuming and labor intensive

which require expensive equipment and professional personnel

and limit their own applications.In recent years

with the rapid development of nanotechnology

nanoparticles have become a research hotspot in the field of foodborne pathogenic bacteria due to their unique physical and chemical properties such as small size

high specific surface area

high reactivity

etc.In addition

the specificity and sensitivity of detection could be improved by modifying the recognition element on the surface of nanoparticles and combining with novel analytical techniques.In this review

the applications of magnetic nanoparticles

noble metal nanoparticles

fluorescent nanoparticles and silica nanoparticles in the detection of foodborne pathogenic bacteria are mainly summarized and compared

aiming at providing a new idea for rapid detection of foodborne pathogenic bacteria.
