| Outline of Final Research Achievements |
A microrheology system has been developed in order to observe the violation of fluctuation dissipation theorems. Using this microrheology system, the viscosity of Laponite suspension systems could be observed during the aging process at room temperature. This observation suggests that the microrheology system can be used to determine the validity of the fluctuation dissipation theorem. In near future, this measurements will be done under shear flow.
