This review paper presents the recent developments in spectroelectrochemical (SEC) technologies. The coupling of spectroscopy and electrochemistry enables SEC to do a detailed and comprehensive study of the electron transfer kinetics and vibrational spectroscopic fingerprint of analytes during electrochemical reactions. Though SEC is a promising technique, the usage of SEC techniques is still limited. Therefore, enough publicity for SEC is required, considering the promising potential in the analysis fields. Unlike previously published review papers primarily focused on the relatively frequently used SEC techniques (ultraviolet-visible SEC and surface-enhanced Raman spectroscopy SEC), the two not-frequently used but promising techniques (nuclear magnetic resonance SEC and dark-field microscopy SEC) have also been studied in detail. This review paper not only focuses on the applications of each SEC method but also details their primary working mechanism. In short, this paper summarizes each SEC technique's working principles, current applications, challenges encountered, and future development directions. In addition, each SEC technique's applicative research directions are detailed and compared in this review work. Furthermore, integrating SEC techniques into microfluidics is becoming a trend in minimized analysis devices. Therefore, the usage of SEC techniques in microfluidics is discussed.
这篇综述文章介绍了光谱电化学（SEC）技术的最新进展。光谱学与电化学的结合使SEC能够对电化学反应过程中分析物的电子转移动力学和振动光谱指纹进行详细而全面的研究。尽管SEC是一项很有前景的技术，但其应用仍然有限。因此，考虑到其在分析领域的巨大潜力，需要对SEC进行充分的宣传。与之前发表的主要关注相对常用的SEC技术（紫外-可见光谱电化学和表面增强拉曼光谱电化学）的综述文章不同，本文还详细研究了两种不太常用但很有前景的技术（核磁共振光谱电化学和暗场显微镜光谱电化学）。这篇综述文章不仅关注每种SEC方法的应用，还详细介绍了它们的主要工作机制。简而言之，本文总结了每种SEC技术的工作原理、当前应用、遇到的挑战以及未来的发展方向。此外，在本综述工作中还详细介绍并比较了每种SEC技术的应用研究方向。此外，将SEC技术集成到微流控中正在成为微型分析设备的一个发展趋势。因此，本文还讨论了SEC技术在微流控中的应用。
