Abstract

Surface enhanced Raman spectroscopy (SERS) displays great advantages in hazardous analysis as a rapid, sensitive “fingerprinting” and on-site analytical tool. However, current SERS sensing system applied in complex actual matrices still face challenges for achieving widespread success. Recent advances in SERS techniques for on-site hazardous analysis has been focused on developing surface molecular imprinted polymers (SMIPs) based SERS methodologies to enhance the selectivity and enrichment ability; to enable higher separation efficiency and accessible identification sites; to integrate the pretreatment procedures with sensing into one unity. In this brief review, the emerging construction strategies and general mechanism study methods for SMIP-SERS sensors are summarized. Furthermore, the application of SMIP-SERS sensors in the actual hazardous analysis will be highlighted, with some fascinating combination toward multi-functional and high-performance on-site sensing. Finally, the new perspectives for future development of SMIP-SERS sensing system were provided.

表面分子印迹技术集成 SERS 传感：现场危险分析的新趋势和未来展望

表面增强拉曼光谱（SERS）作为一种快速、灵敏的 "指纹识别 "和现场分析工具，在危险分析中显示出巨大的优势。然而，目前在复杂实际基质中应用的 SERS 传感系统要取得广泛成功仍面临挑战。用于现场危险品分析的 SERS 技术的最新进展主要集中在开发基于表面分子印迹聚合物（SMIPs）的 SERS 方法，以提高选择性和富集能力；实现更高的分离效率和可访问的识别位点；将预处理程序与传感整合为一体。在这篇简短的综述中，总结了 SMIP-SERS 传感器的新兴构建策略和一般机理研究方法。此外，还将重点介绍 SMIP-SERS 传感器在实际危险分析中的应用，以及在实现多功能和高性能现场传感方面的一些奇妙组合。最后，对 SMIP-SERS 传感系统的未来发展提出了新的展望。
