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.
