“…Hence, achieve the capture of pathogenic bacteria and the sensitization of the Raman signal. Nanosol substrates are simple, inexpensive, and shape‐controlled and are one of the earliest and most popular substrate materials used in SERS detection (Feng et al., 2022; Mitra & Basak, 2022; Zhang, Wang, et al., 2022).…”

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.

“…These nanoplasmonic biosensing platforms may enable amplification-free, accurate, selective, and sensitive detections [ [82] , [83] , [84] ]. Normally, low-cost plasmon-enhanced substrates can be constructed by noble metal nanomaterials such as Au or Ag NPs, nanostars, and nanorods with facile synthetic approaches [ 85 , 86 ]. However, the photolithography instrument, nano metal evaporation setup ($10000-$20000), and plasma etching progress mentioned for fabrication of the sensor chips are not widely available.…”

“…20,38 Color change can be observed with naked eye upon the addition of trace level analytes, favoring establishment of a facile analytical strategy for qualitative analysis without need of analytical instruments. [38][39][40] Moreover, nanoparticle-based arrays have improved in sensitivity and selectivity for trace amounts of UA in samples, thanks to advances in synthesis processes and functionalization stages, which improves the analytical features of simple analytical instruments. For instance, Qin et al reported a colorimetric method for sensing of UA using Au nanorods with an etching process.…”

Gold nanostars (AuNSs) are synthesized by seed mediated growth method. The synthesized AuNSs solution is stable and shows a localized surface plasmon resonance (LSPR) band in the visible range, which is confirmed by UV-visible spectroscopy. Further, the as-synthesized AuNSs were functionalized with melamine and used as a sensor for the colorimetric detection of uric acid (UA). The detection mechanism could be assessed various analytical techniques such as UV-visible spectroscopy, Fourier transforms infrared (FT-IR) spectroscopy, dynamic light scattering (DLS), zeta potential, field emission scanning electron microscopy (FE-SEM) and transmission electron microscopic techniques, respectively. This methods exhibited a good linear regression between the absorption ratio of LSPR band of melamine-AuNSs and the concentration of UA (0 – 120 µM), with the detection limit of 8.50 nM. As a result, UA was quantitatively detected in biofluids by melamine-AuNSs as a colorimetric sensor, revealing melamine-AuNSs-based colorimetric approach could be used as a simple platform for UA assay in biofluids.
