| Research Abstract |
Dynamics heterogeneity is a key concept to understand the glass transition phenomenon; however, it has been difficult to obtain the direct information on the spatial distribution of the mobility of the molecules. In this study, a novel fluorescence microscopy system was developed to observe the dynamics of a single molecule in real time and space. The spatial correlation analysis of the mobility of the molecule revealed that there was no correlation among the molecules at a distance of > 80 nm.
