| Outline of Final Research Achievements |
Optical tweezers, capable of detecting a probe particle with small size for rheological measurements has been developed. The thermal motion of the probe particles dispersed in a supramolecular polymer solution and a polymer physical gel. As a result, we have found that there exist a spatial heterogeneity in their physical properties at the mesoscopic scale. Also, the gelation process of these system was accompanied by the changes in the extent of the heterogeneity and the size scale.
