Daisuke Mizuno, Umeda Katsuhiro, Sugino Yujiro, Kenji Nishizawa, Optical trap and laser interferometry in living cells, Biomedical Imaging and Sensing Conference 2019, BISC 2019, 2019.01, Mechanics of living cell interior are governed by cytoskeletons and cytosol. They are extraordinarily heterogeneous and their physical properties are strongly affected by the internally generated forces. In order to understand the out-ofequilibrium mechanics, we have developed a method of microrheology using laser interferometry and optical trapping technology. This method allowed us to probe mechanics and dynamics in living cells with a high spatio-temporal resolution. Microscopic probes in cells are stably trapped in the presence of vigorous cytoplasmic fluctuations, by employing smooth 3D feedback of a piezo-actuated sample stage. To interpret the data, we present a theory that adapts the fluctuation-dissipation theorem (FDT) to out-of-equilibrium systems. We discuss the interplay between material properties and non-thermal force fluctuations in the living cells that we quantify through the violations of the FDT..

Schmidt, Laser trapping and laser interferometry for high-bandwidth micromechanical probing of biomaterials, Asia Optical Fiber Communication and Optoelectronic Exposition and Conference, AOE 2008, 2008.01, We present techniques based on optical trapping of micron-sized particles as probes and detecting their motion with sub-nanometer accuracy at 100 kHz bandwidth that can measure viscoelastic properties of biomaterials and cells on micrometer scales..
44.	C. F. Schmidt, D. Mizuno, Linear and nonlinear laser-trapping microrheology, Optical Trapping and Optical Micromanipulation IV, 2007.12, [URL], We have developed a high-bandwidth technique for active 2-particle microrheology (AMR) with which we can probe linear and nonlinear responses of soft materials. Micron-sized colloidal probe particles are driven by an oscillating optical trap, and the resulting correlated motions of neighboring particles are detected by laser interferometry. Lock-in detection at the driving frequency and at its second harmonic makes it possible to measure the linear and the non-linear response of the embedding medium at the same time. We demonstrate the sensitivity of the method by detecting a second-harmonic response in water which is of purely geometric origin and which can be fully understood within linear hydrodynamics..

Yasuyuki Kimura, Daisuke Mizuno, Dynamics of nano-sized colloidal particles in a lyotropic lamellar phase, 3rd International Symposium on Slow Dynamics in Complex Systems, 2004.04, [URL], Transport of nano-sized colloidal particles in a dilute lyotropic lamellar phase of a nonionic surfactant has been studied by AC electrophoretic light scattering. The frequency dispersion of complex electrophoretic mobility shows two relaxation processes at about 1kHz (HF relaxation) and a few Hz (LF relaxation). These relaxations are originated from the hindrance of diffusion of particles in characteristic local structures of lamellar phase. The HF relaxation is found to relate the local deformation of membranes induced by particles. The LF one relates the confinement of a particle within persistence length of lamellar orientation..

Takagi, Dynamic measurement of surface properties with Ripplon spectroscopy, Proceedings of the 1998 International Ultrasonics Symposium, 1998.12, Ripplon light scattering technique was applied for the investigation of the mechanical properties of the surface of surfactant solution. The velocity and damping constant of the ripplon were measured for decyl-alcohol solution under periodical modulation of the surface area and the dynamic surface tension was obtained in the frequency range of 10^-3-10^-1 Hz. The relaxation of surface elasticity due to the adsorption and desorption of the surfactant molecules was successfully observed..

At the concentration above 2w%, an almost single relaxation related with the cooparative diffusion of membranes is detected. The dynamic correlation lengh is evaluated from the diffusion constant to be a little larger than that obtained for the L_α phase. At the concentration below 2w%, we can find the crossover behavior Γ∝q^2 to Γ∝q^3 in the dispersion relation between the inverse correlation time Γ and the scattering wavenumber q..
