Observation of electrochemical reaction and biological specimen by novel analytical technique combined with room-temperature ionic liquid and scanning electron microscope

Room-temperature ionic liquid (RTIL) that is a liquid salt at or below room temperature is expected to be an innovative functional solvent and a liquid material due to its anomalous physicochemical properties such as negligible vapor pressure, flame resistance, and relatively-high conductivity. With an eye on what RTIL has negligible vapor pressure, we have created the analytical technique combined with RTIL and secondary electron microscope (SEM). In this paper, we report several RTIL-based SEM techniques that will be a useful analytical method in both electrochemistry and life science. The aim of this study is to show the utility of the RTIL-based SEM techniques.
