“…Mixed nanomaterial substrates have advantages in the detection of some substances. Some studies have shown that by mixing different materials [ 87 ], the Raman signal of target molecules on the substrate surface can be enhanced to achieve sensitive detection of target substances [ 88 ]. In order to achieve rapid SERS analysis of target substances in complex matrices, a high-activity enhanced substrate is needed.…”

Surface-enhanced Raman spectroscopy (SERS) is an emerging technology that combines Raman spectroscopy and nanotechnology with great potential. This technology can accurately characterize molecular adsorption behavior and molecular structure. Moreover, it can provide rapid and sensitive detection of molecules and trace substances. In practical application, SERS has the advantages of portability, no need for sample pretreatment, rapid analysis, high sensitivity, and ‘fingerprint’ recognition. Thus, it has great potential in food safety detection. Alcoholic beverages have a long history of production in the world. Currently, a variety of popular products have been developed. With the continuous development of the alcoholic beverage industry, simple, on-site, and sensitive detection methods are necessary. In this paper, the basic principle, development history, and research progress of SERS are summarized. In view of the chemical composition, the beneficial and toxic components of alcoholic beverages and the practical application of SERS in alcoholic beverage analysis are reviewed. The feasibility and future development of SERS are also summarized and prospected. This review provides data and reference for the future development of SERS technology and its application in food analysis.

“…SERS is emerging as a powerful technique in the field of food science and technology especially for food inspection [ 91 , 92 ]. In principle, it enhances the Raman signals through adsorption of analytes close to the vicinity of localized surface plasmon resonance (hot spots) generated by metal nanostructures depending on the variation in their roughness [ 93 , 94 ]. Moreover, the integration of an engineered plasmonic nanostructure with other functional materials enables a synergistic modulation of both chemical and electromagnetic properties of the hybrid substrate for efficient SERS analysis [ 95 ].…”

Mycotoxins (MYTs), a class of low molecular weight secondary metabolites produced by filamentous fungi in food and feed, pose serious global threat to both human health and world economy. Due to their mutagenic, teratogenic, carcinogenic and immunosuppressive effects, the International Agency for Research on Cancer has classified various MYTs under Group 1 to 3 category with aflatoxins being designated under Group 1 category (carcinogenic to humans). Also, the presence of MYTs in trace amounts in diverse food matrices necessitates exploration of highly sensitive methods for onsite analysis. Although conventional chromatographic methods are highly sensitive, they are expensive, tedious and cannot be applied for rapid onsite analysis. In recent years the application of nanomaterials especially carbon-based nanomaterials (CNMs) in the fabrication of low-cost and miniaturized electrochemical and optical sensors has enabled rapid onsite analysis of MYTs with high sensitivity and specificity. Moreover, the CNMs are employed as effective solid phase extraction (SPE) adsorbents possessing high specific surface area for effective enrichment of MYTs to improve the sensitivity of chromatographic methods for MYT analysis in food. This article aims to overview the recent trends in the application of CNMs as SPE adsorbents for sample pretreatment in chromatographic methods as well as in the fabrication of highly sensitive electrochemical and optical sensors for rapid analysis of MYTs in food. Initially, the efficiency of various functionalized CNMs developed recently as adsorbent in packed SPE cartridges and dispersive SPE adsorbent/purification powder is discussed. Then, their application in the development of various electrochemical immunosensors involving functionalized carbon nanotubes/nanofibers, graphene oxide, reduced graphene oxide and graphene quantum dots is summarized. In addition, the recent trends in the use of CNMs for fabrication of electrochemical and fluorescence aptasensors as well as some other colorimetry, fluorometry, surface-enhanced Raman spectroscopy and electrochemical based sensors are compared and tabulated. Collectively, this review article can provide a research update on analysis of MYTs by carbon-based nanomaterials paving a way for identifying future perspectives.

Although diffusion gradient in the thin-film technique (DGT) is highly regarded in environmental analysis, the traditional DGT devices cannot serve as sensing devices but in situ sampling devices. Here we report a surface enhanced Raman scattering (SERS) responsive DGT sensing device (SERS-DGT Sensor) capable of on-site determination of organic contaminants underwater. This is achieved by innovatively utilizing a SERS responsive liquid suspension of Au nanoparticles supported on graphene oxide (AuNPs@GO) as the DGT binding phase. Liquid suspension is synthesized via a combined secondary growth and molecular welding approach and used as DGT binding phase AuNPs@GO exhibit good SERS activity, aqueous stability, and adsorption performance. Based on the development time range of 24−144 h, the measurement of sulfadiazine (SMT) by SERS-DGT Sensor is evaluated in the concentration range of 0.3289−2631 ng mL −1 . The SERS-DGT sampler is valid for measuring SMT under a wide range of environmental conditions (i.e, pH 5−9, ionic strength 0.0001−0.05 mol L −1 NaCl, DOM concentrations 0−100 mg L −1 , the values of TC: SMT ≤ 20 and MNZ: SMT ≤ 20). SERS-DGT Sensor is applied to the practical test of SMT content in pig breeding wastewater, and compared with the grab sampling method, the results confirm that this novel hyphenated technique exhibits good accuracy and precision. The platform proves to be versatile by extending the method to the monitoring of rhodamine 6G, metronidazole, fluoxetine, and enrofloxacin. In this article, SERS-DGT Sensor, a platform for directly on-site sensing of organic DGT, holds great potential for in situ sampling and on-site sensing for a wide range of organics and provides a new idea for environmental monitoring.
