ATP-induced reconfiguration of the micro-viscoelasticity of cardiac and skeletal myosin solutions
Pablo Domínguez-García, Jose R. Pinto, Ana Akrap +1
We study the high-frequency micro-mechanical response of suspensions composed by cardiac and skeletal muscle myosin by optical trapping interferometry. We observe that in low ionic…
Micro-mechanical response and power-law exponents from the longitudinal fluctuations of F-actin solutions
Pablo Domínguez-García, Jose R. Pinto, Ana Akrap +1
We investigate the local fluctuations of filamentous actin (F-actin), with focus on the skeletal thin filament, using single-particle optical trapping interferometry. This experime…
Interplay between optical, viscous and elastic forces on an optically trapped Brownian particle immersed in a viscoelastic fluid
P. Domínguez-García, László Forró, Sylvia Jeney
We provide a detailed study of the interplay between the different interactions which appear in the Brownian motion of a micronsized sphere immersed in a viscoelastic fluid measure…
Accounting for inertia effects to access the high-frequency microrheology of viscoelastic fluids
P. Domínguez-García, Frédéric Cardinaux, Elena Bertseva +3
We study the Brownian motion of microbeads immersed in water and in a viscoelastic wormlike micelles solution by optical trapping interferometry and diffusing wave spectroscopy. Th…
Evidence of hydrodynamic and subdiffusive motion of tracers in a viscoelastic medium
Denis S. Grebenkov, Mahsa Vahabi, Elena Bertseva +2
We propose a theoretical model which relies on the generalized Langevin equation and may account for various dynamical features of the thermal motion of organelles, vesicles or mac…
High-resolution detection of Brownian motion for quantitative Optical Tweezers experiments
Matthias Grimm, Thomas Franosch, Sylvia Jeney
We have developed a new in situ method to calibrate optical tweezers experiments and simultaneously measure the size of the trapped particle or the viscosity of the surrounding flu…
