摘　　要：Surface enhanced Raman spectroscopy(SERS)offers many advantages for the fast and sensitive detection of specific compounds,metal ions or pathogens in foods,motivating to its increasing utilization in food safety.SERS-tags,typically constructed using signal enhanced substrate,Raman reporter molecules,a biocompatible protective layer and a specific recognition element,provide a powerful tool for the analysis of food hazards.This article reviews recent progress in the development of SERS-tags for food safety assessment covering SERS-tags with characteristic peaks in the“fingerprint”region(800-1800 cm-1)and the“biological-silent”region(1800-2800 cm-1).Following a brief description of SERS substrates,the design,synthesis and applications of SERS-tag are explored in detail.The application of SERS-tags technology for the detection of microorganisms,pesticides and antibiotics are then investigated.Finally,the prospects of using SERS-tag in real-world food safety analysis are critically discussed.
