Background

The irrational usage of chemical substances including pesticides and drugs in agricultural and food production is a significant food safety issue due to its residues. Therefore, the detection of harmful residues in foods is an indispensable step for guaranteeing the consumer's health. Conventional methods, such as HPLC, GC-MS and LC-MS are accurate enough, but they fail to meet the requirements of the modern industry for rapid and on-line detection. Novel reliable techniques should thus be developed as alternatives.

Scope and Approach

In this review, fundamentals of surface-enhanced Raman spectroscopy (SERS) is introduced. Recent advances in its usage for detecting harmful chemical residues in agricultural products including pesticides, antibiotics and β₂-adrenergic agonists are discussed by two typical ways of detection improvement, and the advantages of SERS are addressed. Finally, future trends to routine use of SERS applications in harmful residues are presented.

Key Findings and Conclusions

SERS is a promising detection technique for the detection of common harmful chemical residues with merits of simple sampling, rapid data collection and non-destructiveness. Despite rapid developments in the technology, there is much studies should be done before SERS could be used as a daily tool for the industry.

表面增强拉曼光谱（SERS）：一种用于快速检测常见有害化学残留物的新颖可靠技术

背景

由于其残留物，在农业和食品生产中不合理使用包括农药和药物在内的化学物质是一个重大的食品安全问题。因此，食品中有害残留物的检测是保证消费者健康的必不可少的步骤。常规方法（例如HPLC，GC-MS和LC-MS）足够准确，但是它们不能满足现代工业对快速和在线检测的要求。因此，应该开发出新颖可靠的技术作为替代方案。

范围和方法

在这篇综述中，介绍了表面增强拉曼光谱（SERS）的基本原理。在它的使用，用于检测在农产品包括杀虫剂，抗生素和β有害的化学残留物的最新进展₂ -肾上腺素能受体激动剂通过的检测改善两种典型方式进行了讨论，并且SERS的优点解决。最后，介绍了在有害残留物中常规使用SERS应用的未来趋势。

主要发现和结论

SERS是一种用于检测常见有害化学残留物的有前途的检测技术，它具有简单的采样，快速的数据收集和无损检测的优点。尽管技术发展迅速，但在将SERS用作该行业的日常工具之前，还需要进行大量研究。
