摘要
最近10年,针尖增强拉曼光谱技术(TERS)以其极高的空间分辨率和探测灵敏度受到了人们的重视。针尖增强拉曼光谱技术为纳米科学与生命科学等学科的研究提供了强有力的工具,使得纳米尺度光谱学研究成为现实。简述了针尖增强拉曼光谱技术的基本原理,着重讨论了针尖增强拉曼光谱系统的结构、设计方法和评价指标。介绍了针尖增强拉曼光谱技术的最新应用和研究进展,并对目前面对的前沿问题和今后的发展方向进行了分析。
The tip-enhanced Raman spectroscopy (TERS) has drawn much attention from the academic community due to its high spatial resolution and detection sensitivity in the last decade. The TERS method provides a powerful tool for the nano-material science and life science. It makes nano- spectroscopy come true. The basic principles of TERS are briefly described, and the configuration, design method and evaluation criterion of TERS systems are discussed. The new applications and research of TERS are introduced, and the frontier topics, key technical issues are analyzed.
