Fluorescence single molecule observation is a technique to visualize individual movements and reactions of probe molecules such as fluorescent dyes and proteins. It has been developed mainly in the fields of biophysics and cell biology as an observation method under physiological conditions, i.e., in aqueous solutions. We have applied fluorescence single molecule observation to observe molecular behavior at the interface between organic solvents and solid substrates as a new method to investigate the molecular mechanism of lubrication. In this study, the single molecule fluorescence observation was applied to a metal surface, because lubrication and friction are generally handled on the surfaces of metals, such as machine tools and engine. fluorescence may be quenched on metal surfaces.
