Abstract(in English) | We can obtain relaxation time and corresponding viscosity of solution by capturing the thermal motions of optically trapped microspheres. We investigated easy-to-use three dimensional position tracking microscopy with high frame rate by a point light source of single LED. In contrast to the normal homogeneous fluid, in a collagen solution the motion of probe particle shows extraordinary distorted distribution, which indicates surrounding polymer networks deform with relatively slow dynamics. |
