| Outline of Final Research Achievements |
With the development of the new experimental technique called microrheology, many knowledges concerning cell rheology have been accumulating all over the world in the last decade. In this research project, with the aim to understand the universal behaviors in cell rheology within soft matter physics and nonequilibrium physics, we have developed fundamental theories for microrheology that is applicable to inhomogeneous and nonequilibrium systems. Furthermore, we have established a new microrheology method that is suitable for investigating mechanical responses in cells coated with biomembranes. In particular, we have established the followings: (i) basic theory for membrane microrhelogy, (ii) active microrheology in multi-component media, and (iii) detection of non-thermal fluctuations by using microrhelogy methods.
