Tip-enhanced Raman scattering (TERS) has recently attracted remarkable attention as a novel nano-spectroscopy technique. TERS, which provides site-specific information, can be performed on any material surface regardless of morphology. Moreover, it can be applied in various environments, such as ambient air, ultrahigh vacuum (UHV), solutions, and electrochemical environments. This review reports on one hand progress of TERS for the last two decades, and on the other hand, its challenges in very recent years. Part of the progress of TERS starts with the prehistory and history of TERS, and then, the characteristics and advantages of TERS are described. Significant emphasis is put on the development of TERS instrumentation and equipment such as ultrahigh vacuum TERS, liquid TERS, electrochemical-TERS, and tip-preparations. Applications of TERS, particularly those with nanocarbons, biological materials, and surface and interface analysis, are mentioned in some detail. In the part on challenges, we focus on the very recent advances in TERS; progress in spatial resolution to the angstrom scale is the hottest topic. Recent TERS studies performed under UHV, for example chemical imaging at the angstrom scale and Raman detection of bond breaking and making of a chemisorbed up-standing single molecules at single-bond level, are reviewed. Of course, there is no clear border between the two parts. In the last part the perspective of TERS is discussed.
作为一种新型的纳米光谱技术，针尖增强拉曼散射（TERS）最近引起了广泛关注。TERS能够提供特定位置的信息，可在任何材料表面进行，而不受其形态的影响。此外，它还可应用于各种环境，如环境空气、超高真空（UHV）、溶液以及电化学环境。本综述一方面报道了TERS在过去二十年中的进展，另一方面也阐述了其近年来面临的挑战。TERS的部分进展始于其史前史和历史，然后描述了TERS的特点和优势。重点介绍了TERS仪器设备的发展，如超高真空TERS、液体TERS、电化学TERS以及针尖制备。详细提及了TERS的应用，特别是在纳米碳、生物材料以及表面和界面分析方面的应用。在挑战部分，我们关注TERS的最新进展；空间分辨率达到埃尺度的进展是最热门的话题。综述了最近在超高真空下进行的TERS研究，例如埃尺度的化学成像以及在单键水平对化学吸附直立单分子的键断裂和形成进行拉曼检测。当然，这两部分之间并没有明确的界限。在最后一部分讨论了TERS的前景。
