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…
Brownian dynamics simulations to explore experimental microsphere diffusion with optical tweezers
Manuel Pancorbo, Miguel A. Rubio, P. Domínguez-García
We develop two-dimensional Brownian dynamics simulations to examine the motion of disks under thermal fluctuations and Hookean forces. Our simulations are designed to be experiment…
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…
