Surface-enhanced Raman scattering (SERS) spectroscopy has evolved into a cross-disciplinary analytical technique by unveiling relevant chemical, biological, material, and structural information. The focus of this review is on two critical properties for successfully expanding applications of SERS spectroscopy: quality of the plasmonic substrate and molecule localization to the substrate. In this review, we discuss recent work on quantifying SERS distance dependence, key factors for substrate characterization and performance evaluation, expansion of SERS applications through substrate development for UV plasmonics and short-distance capture strategies for optimizing analyte-surface structures. After surveying the recent developments of these seemingly disparate fields, we suggest new research directions that may originate from a synergistic blend of all the herein discussed topics. Finally, we discuss major challenges and open questions related to the application of SERS for understanding of chemical processes at the nanoscale, with special interest on in situ catalysts and biosensing.

通过通用的纳米材料工程扩展SERS的应用

通过增强相关的化学,生物学,材料和结构信息,表面增强拉曼散射(SERS)光谱已发展成为一种跨学科的分析技术。这篇综述的重点是成功扩展SERS光谱学应用的两个关键特性:等离激元底物的质量和分子对底物的定位。在这篇综述中,我们讨论了有关量化SERS距离依赖性,底物表征和性能评估的关键因素,通过底物开发用于等离激元的UV等离子体的SERS应用以及优化分析物表面结构的短距离捕获策略的最新工作。在调查了这些看似完全不同的领域的最新发展之后,我们建议提出新的研究方向,这些方向可能来自本文讨论的所有主题的协同融合。最后,我们讨论了与SERS的应用相关的主要挑战和未解决的问题,以了解纳米级的化学过程,并特别关注原位催化剂和生物传感。
