“…The uniformity of SERS signals was approximately 10fold, and the signal intensity was approximately 27-fold higher aer modulating the substrate distribution with magnets, consistent with previous reports. [11][12][13]25 In the absence of magnetic modulation, the widely separated nanoparticles resulted in a scattered and inhomogeneous hotspot distribution. By contrast, the presence of an external magnetic eld decreased the spacing between the FA particles, leading to plasma formation on the surface of the substrate and enhanced electromagnetic elds between the AuNPs.…”

“…The flexible solid‐phase SERS substrates are metal nanomodified flexible SERS materials using fiber paper, GO, polymers, and other flexible materials as the primary substrates (Bharati & Soma, 2021). The flexible SERS substrates have demonstrated excellent promise in SERS assays due to their superior mechanical resistance, facile transportation, easy tailoring of size/shape, low cost, and easy handling.…”

Rapid control and prevention of diseases caused by foodborne pathogens is one of the existing food safety regulatory issues faced by various countries and has received wide attention from all sectors of society. The development of rapid and reliable detection methods for foodborne pathogens remains a hot research area for food safety and public health because of the limitations of complex steps, time-consuming, low sensitivity, or poor selectivity of commonly used methods.Surface-enhanced Raman spectroscopy (SERS), as a novel spectroscopic technique, has the advantages of high sensitivity, selectivity, rapid and nondestructive detection and has exhibited broad application prospects in the determination of pathogenic bacteria. In this study, the enhancement mechanisms of SERS are briefly introduced, then the characteristics and properties of liquid-phase, rigid solid-phase, and flexible solid-phase are categorized. Furthermore, a comprehensive review of the advances in label-free or label-based SERS strategies and SERS-compatible techniques for the detection of foodborne pathogens is provided, and the advantages and disadvantages of these methods are reviewed.Finally, the current challenges of SERS technology applied in practical applications are listed, and the possible development trends of SERS in the field of foodborne pathogens detection in the future are discussed.
