The comprehension of supersaturated phenomena in solution is one of the most important issue. For example, development of industrial crystallization processes, elucidation of bio-mineralization process, and protein abnormal aggregation process. In this study, we focused on the development of a novel method to observe the solution structure of supersaturated solution in nano-scale level by monitoring dissolved gold nanocrystals dynamics also known as Diffracted X-ray Tracking (DXT). From this study, we established a dissolution system of gold nanocrystals on the sodium acetate solution (6.4 M) and we succeeded in observing rotational dynamics of a dispersed single gold nanocrystal in 100 μs time scale resolution.
