Environmental pollution, a major problem worldwide, poses considerable threat to human health and ecological environment. Efficient and reliable detection technologies, which focus on the appearance of emerging environmental and trace pollutants, are urgently needed. Surface-enhanced Raman scattering (SERS) has become an attractive analytical tool for sensing trace targets in environmental field because of its inherent molecular fingerprint specificity and high sensitivity. In this review, we focused on the recent developments in the integration of magnetic nanoparticles (MNPs) with SERS for facilitating sensitive detection of environmental pollutants. An overview and classification of different types of MNPs for SERS detection were initially provided, enabling us to categorize the huge amount of literature that was available in the interdisciplinary research field of MNPs based SERS technology. Then, the basic working principles and applications of MNPs in SERS detection were presented. Subsequently, the detection technologies integrating MNPs with SERS that eventually were used for the detection of various environmental pollutions were reviewed. Finally, the advantages of MNP-basedSERS detection technology for environmental pollutants were concluded, and the current challenges and future outlook of this technology in practical applications were highlighted. The application of the MNPs-basedSERS techniques for environmental analysis will be significantly advanced with the great progresses of the nanotechnologies, optics, and materials.
环境污染是一个全球性的重大问题，对人类健康和生态环境构成了相当大的威胁。迫切需要高效、可靠的检测技术，这些技术专注于新兴环境和痕量污染物的出现。由于表面增强拉曼散射（SERS）具有固有分子指纹特异性和高灵敏度，因此已成为环境领域中用于感测痕量目标的一种有吸引力的分析工具。在这篇综述中，我们重点关注了将磁性纳米粒子（MNPs）与 SERS 集成以促进环境污染物敏感检测的最新进展。首先提供了不同类型的 MNPs 用于 SERS 检测的概述和分类，使我们能够对基于 MNPs 的 SERS 技术的跨学科研究领域中的大量文献进行分类。然后，介绍了 MNPs 在 SERS 检测中的基本工作原理和应用。随后，综述了用于检测各种环境污染物的与 MNPs 集成的 SERS 检测技术。最后，总结了基于 MNPs 的 SERS 检测技术用于环境污染物检测的优势，并强调了该技术在实际应用中的当前挑战和未来展望。随着纳米技术、光学和材料的巨大进步，基于 MNPs 的 SERS 技术在环境分析中的应用将得到显著推进。
