| Abstract(in English) | Optical tweezers have been widely used in biological applications such as cell sorting, cell fusion, intracellular surgery, etc. Recently, using this technique, the measurement of local rheological properties in soft materials has become possible. However, the rheological analysis using optical tweezers has often been limited to the measurements at room temperature. We here introduce a simple and facile setup of optical tweezers capable of carrying out temperature-dependent microrheological measurements. By using the optical tweezers, we examine the frequency and temperature dependences of the viscoelastic functions in a worm-like micelle solution. As a result, the optical tweezers setup presented here could be employed as a tool for the rheological measurements of soft materials. |
