摘要

表面增强拉曼散射（SERS）技术在快速检测植物源食品中的农药残留方面具有独特的优势，可降低检测限并提高准确性。植物源中药材的来源与植物源食品类似，但由于中药材表面粗糙、成分复杂，其农药残留的检测仍主要依赖传统方法，费时费力，无法满足市场对便携性的需求。将柔性纳米材料和 SERS 技术应用于这一领域，可以实现便携式的快速准确检测。因此，在这篇综述中，我们总结了 SERS 技术的基本原理和特点，尤其侧重于 SERS 在农产品农药残留分析中的应用。本文从样品预处理、SERS 基质和数据处理三个主要方向总结了该领域的最新研究进展。本文还讨论了 SERS 技术的前景和局限性，以期为快速检测中药材中的农药残留提供理论支持。

Research Status in the Use of Surface-Enhanced Raman Scattering (SERS) to Detect Pesticide Residues in Foods and Plant-Derived Chinese Herbal Medicines

Surface-enhanced Raman scattering (SERS) technology has unique advantages in the rapid detection of pesticides in plant-derived foods, leading to reduced detection limits and increased accuracy. Plant-derived Chinese herbal medicines have similar sources to plant-derived foods; however, due to the rough surfaces and complex compositions of herbal medicines, the detection of pesticide residues in this context continues to rely heavily on traditional methods, which are time consuming and laborious and are unable to meet market demands for portability. The application of flexible nanomaterials and SERS technology in this realm would allow rapid and accurate detection in a portable format. Therefore, in this review, we summarize the underlying principles and characteristics of SERS technology, with particular focus on applications of SERS for the analysis of pesticide residues in agricultural products. This paper summarizes recent research progress in the field from three main directions: sample pretreatment, SERS substrates, and data processing. The prospects and limitations of SERS technology are also discussed, in order to provide theoretical support for rapid detection of pesticide residues in Chinese herbal medicines.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
