Surface-enhanced Raman spectroscopy is an alternative detection tool for monitoring food security. However, there is still a lack of a conclusion of SERS detection with respect to pesticides and real sample analysis, and the summary of intelligent algorithms in SERS is also a blank. In this review, a comprehensive report of pesticides detection using SERS technology is given. The SERS detection characteristics of different types of pesticides and the influence of substrate on inspection are discussed and compared by the typical ways of classification. The key points, including the progress in real sample analysis and Raman data processing methods with intelligent algorithm, are highlighted. Lastly, major challenges and future research trends of SERS analysis of pesticide residue are also addressed. SERS has been proven to be a powerful technique for rapid test of residue pesticides in complex food matrices, but there still is a tremendous development space for future research.

“…The vacuumassisted filtration accelerates the removal of the liquid phase maintaining the solid phase on the filter paper surface until to reach self-standing films after complete elimination of solvent. A standard procedure concerns the filtration of nanocomposites in PTFE membranes followed by drying of solid material for a posterior step in which the film is peeled off to be applied as SERS substrate [34,58]. Alternatively, Bhunia et al reported the development of flexible supports of polydimethylsiloxane embedding carbon dots for the following step of coating with silver nanoparticles, as schematically drawn in Fig.…”

Carbon dots and carbon dots-based nanocomposites have found a myriad of technological applications. Despite the primary use of carbon dots as catalysts in the reduction process to form metal nanoparticles, their strong interaction with metal nanostructures in nanocomposites can be further exploited. By tuning the emission of carbon dots and the absorption band of metal nanoparticles, it is possible to reach adequate surface-enhanced Raman scattering (SERS) from the resulting nanocomposites. Herein, it is reported the state-of-art in metal/carbon dots nanocomposites applied as active elements for SERS devices in the detection of traces of analytes. Strategies of synthesis, morphology (aggregation and anti-aggregation methods) and the improvement in the homogeneous distribution of noble metal nanoparticles on substrates have been discussed to reach the best performance for highly efficient SERS devices.

Rapid and accurate analysis of multiple targets in complex samples is still a big challenge in the fast detection field. Herein, we developed a rapid and accurate strategy for simultaneous quantification of trace multiple antibiotic residues in complex aquatic samples by surface-enhanced Raman scattering (SERS) using a Ti 3 C 2 T x /DNA/Ag membrane substrate. This membrane substrate was proven to have good uniformity, reproducibility, stability, and SERS activity by a series of characterizations. Also, this substrate combined excellent electromagnetic enhancement and chemical enhancement effects, which endowed it with good sensitivity and selectivity during SERS analysis. It achieved the integration of multitarget separation, enrichment, and in situ detection, which significantly improved the selectivity, sensitivity, accuracy, and detection throughput by membrane substrate coupling with SERS for real-sample analysis. Finally, this rapid SERS analysis strategy was successfully applied to the simultaneous quantification of trace nitrofurantoin (NFT) and ofloxacin (OFX) in aquatic samples. It was observed that trace NFT and OFX were actually detected and simultaneously quantified to be 8.0−13.7 and 42.6−49.1 μg/kg in aquatic samples, respectively, with good recoveries of 88.0−107% and relative standard deviations of 0.3−5.5%. The results were verified by a traditional high-performance liquid chromatography method with relative errors of −9.8 to 5.3%. This strategy provided a methodological reference for accurate SERS quantification of multiple targets in complex samples.
