In which orientation does adenine adsorb on gold and silver surfaces? This question has been a matter of debate for over 30 years. Since the dawn of surface-enhanced Raman spectroscopy (SERS); it and other techniques such as tip-enhanced Raman spectroscopy (TERS), surface-enhanced infrared absorption spectroscopy (SEIRAS), scanning tunneling microscopy (STM), density functional theory (DFT) simulations, and more, have been used in many attempts to answer this seemingly straightforward, yet controversial, question. Herein, the timeline and recent advances on this topic are explored, and the frequently contradictory findings are put into context and discussed.
腺嘌呤在金和银表面以何种取向吸附？这个问题已经争论了30多年。自表面增强拉曼光谱（SERS）出现以来，它以及其他技术，如针尖增强拉曼光谱（TERS）、表面增强红外吸收光谱（SEIRAS）、扫描隧道显微镜（STM）、密度泛函理论（DFT）模拟等等，已被多次用于尝试回答这个看似简单却颇具争议的问题。本文探讨了该主题的时间线和最新进展，并对经常相互矛盾的研究结果进行了背景介绍和讨论。
