Spectroscopic methods with high spatial resolution are essential to understand the physical and chemical properties of nanoscale materials including biological and chemical materials. Tip-enhanced Raman spectroscopy (TERS) is a combination of surface-enhanced Raman spectroscopy (SERS) and scanning probe microscopy (SPM), which can provide high-resolution topographic and spectral information simultaneously below the diffraction limit of light. Even examples of sub-nanometer resolution have been demonstrated. This review intends to give an introduction to TERS, focusing on its basic principle and the experimental setup, the strengths followed by recent applications, developments, and perspectives in this field.
具有高空间分辨率的光谱方法对于理解包括生物和化学材料在内的纳米级材料的物理和化学性质至关重要。针尖增强拉曼光谱（TERS）是表面增强拉曼光谱（SERS）和扫描探针显微镜（SPM）的结合，它可以在光的衍射极限以下同时提供高分辨率的形貌和光谱信息。甚至已经证明了亚纳米分辨率的实例。本综述旨在介绍TERS，重点关注其基本原理和实验装置、优势以及该领域的最新应用、发展和前景。
