Turbulent dynamics of epithelial cell cultures
C. Blanch-Mercader, V. Yashunsky, S. Garcia +3
In vitro epithelial monolayers exhibit a rich repertoire of collective dynamical behaviours according to microenvironment mechanical features. We investigate the statistical and dy…
Bistability, oscillations and bidirectional motion of ensemble of hydrodynamically-coupled molecular motors
P. Malgaretti, I. Pagonabarraga, J. F. Joanny
We analyze the collective behavior of hydrodynamically coupled molecular motors. We show that the local fluxes induced by motors displacement can induce the experimentally observed…
Active elastohydrodynamics of vesicles in narrow, blind constrictions
Thomas G. Fai, Remy Kusters, Jens Harting +2
Fluid-resistance limited transport of vesicles through narrow constrictions is a recurring theme in many biological and engineering applications. Inspired by the motor-driven movem…
Pressure and Flow of Exponentially Self-Correlated Active Particles
Cato Sandford, Alexander Y. Grosberg, Jean-François Joanny
Microscopic swimming particles, which dissipate energy to execute persistent directed motion, are a classic example of a non-equilibrium system. We investigate the non-interacting…
Hydrodynamic instabilities, waves and turbulence in spreading epithelia
C. Blanch-Mercader, J. Casademunt
We present a hydrodynamic model of spreading epithelial monolayers as polar viscous fluids, with active contractility and traction on the substrate. The combination of both active…
Probing the Structure and in Silico Stability of Cargo Loaded DNA Icosahedron using MD Simulations
Himanshu Joshi, Dhiraj Bhatia, Yamuna Krishnan +1
Platonic solids such as polyhedra based on DNA have been deployed for multifarious applications such as RNAi delivery, biological targeting and bioimaging. All of these application…
