“…Surface‐enhanced Raman scattering (SERS) methods are widely used for the detection of pathogens, mycotoxins, pesticides, and other food contaminants in food because of their excellent detection performance such as high sensitivity and simple operation (Chang et al., 2023). It vibrates in different ways and degrees mainly by absorbing different energy of excited light, and the mode and frequency are determined by the properties of the material.…”

Food contaminants have consistently posed a serious threat to human health and have caused various food safety problems. The most common techniques currently used for the detection of food contaminants, include instrumental and immunoassay methods; however, these traditional methods have shown some limitations when applied to the analysis of food contaminants. Therefore, in recent years, more and more researchers have been devoted to the development of rapid, reliable, sensitive, and suitable detection techniques for the detection of food contaminants in food matrices. In this review, we first classify the analytical methods proposed in recent years into colorimetric methods, fluorescence methods, photoelectrochemical methods, electrochemical methods, nucleic acid amplification methods, and other methods, and illustrate their detection principles. In addition, the paper highlights the strategies and recent research advances for each method through typical application examples. Finally, the future perspectives of these analytical methods are presented. We hope that this review will provide researchers with valuable insights to guide the sensitive detection of food contaminants.

As a promising spectroscopic technique, surface enhanced raman spectroscopy (SERS) has been intensively used in bio/chemical sensing, attributing to its unique advantages of ultrasensitive and accurate detection of trace amounts of analytes, high specific fingerprint-like features, fast response, and noninvasive sensing. The robustness and consistency of SERS signals in practical analytical applications highly rely on the composition, structural morphology, and uniformity of SERS substrates. These factors play a pivotal role in determining the intensity and reproducibility of the detected signals. SERS substrates based on ordered nanostructures that are fabricated from anodic aluminum oxide (AAO)-templateassisted approaches are of significant interest due to their cost effectiveness, scalability, precise structural control, and exceptionally ordered features. In this review, recent progress in SERS substrates with high sensitivity and reproducibility prepared from AAO templates is highlighted. We emphasize the optimization strategies toward achieving efficient SERS-active substrates by fine-tuning the size, composition, and morphology of AAO-derived ordered nanostructures. Furthermore, we delve into the discussion of flexible and smart SERS substrates, while also exploring key aspects pertinent to further amplifying SERS signals. Overall, this review aims to offer insights into the future integration of the AAO templates technique with SERS, providing crucial perspectives for forthcoming research in this field.

“…Therefore, a great deal of effort has been made by many researchers to fabricate new sorts of plasmonic core-shell nanostructure. [19][20][21][22][23] For instance, Wang et al proposed the assembly of silver-coated gold nanocubes on nanocrystalline cellulose to detect pesticide residue. 24 Furthermore, some researchers proposed the insertion of a layer of Raman molecules into the core-shell particles to construct coremolecule-shell (CMS) nanostructures to achieve more applications.…”
