Since the discovery of the phenomenon of surface-enhanced Raman scattering (SERS), it has gradually become an important tool for the analysis of material compositions and structures. The applications of SERS have been expanded from the fields of environmental and materials science to biomedicine due to the extremely high sensitivity and non-destructiveness of SERS-based analytical technology that even allows single-molecule detection. This article provides a comprehensive overview of the surface-enhanced Raman scattering (SERS) phenomenon. The content is divided into several main sections: basic principles and the significance of Raman spectroscopy; historical advancements and technological progress in SERS; and various practical applications across different fields. We also discuss how electromagnetic fields contribute to the SERS effect, the role of chemical interactions in enhancing Raman signals, a modeling and computational approaches to understand and predict SERS effects.
自表面增强拉曼散射（SERS）现象被发现以来，它已逐渐成为分析材料成分和结构的重要工具。由于基于SERS的分析技术具有极高的灵敏度和非破坏性，甚至能够实现单分子检测，SERS的应用领域已从环境和材料科学领域扩展到生物医学领域。本文全面概述了表面增强拉曼散射（SERS）现象。内容分为几个主要部分：拉曼光谱的基本原理及其意义；SERS的历史进展和技术进步；以及不同领域的各种实际应用。我们还讨论了电磁场如何对SERS效应产生影响、化学相互作用在增强拉曼信号中的作用、用于理解和预测SERS效应的建模和计算方法。
