Tubulation pattern of membrane vesicles coated with bio filaments
Gaurav Kumar, N. Ramakrishnan, Anirban Sain
Narrow membrane tubes are commonly pulled out from the surface of phospholipid vesicles using forces applied either through laser or magnetic tweezers or through the action of proc…
Computational investigation of multivalent binding of a ligand coated particle: Role of shape, size and ligand heterogeneity from a free energy landscape perspective
Matt McKenzie, Sung Min Ha, Aravind Rammohan +2
We utilize a multiscale modeling framework to study the effect of shape, size and ligand composition on the efficacy of binding of a ligand-coated-particle to a substrate functiona…
Motion of a nano-ellipsoid in a cylindrical vessel flow: Brownian and hydrodynamic interactions
N. Ramakrishnan, Y. Wang, D. M. Eckmann +2
We present comprehensive numerical studies of the motion of a buoyant or a nearly neutrally buoyant nano-sized ellipsoidal particle in a fluid filled cylindrical tube without or wi…
Excess area dependent scaling behavior of nano-sized membrane tethers
N. Ramakrishnan, Arpita Roychoudhury, David M. Eckmann +6
Thermal fluctuations in cell membranes manifest as an excess area () which governs a multitude of physical process at the sub-micron scale. We present a theoreti…
Mesoscale computational studies of membrane bilayer remodeling by curvature-inducing proteins
N. Ramakrishnan, P. B. Sunil Kumar, Ravi Radhakrishnan
Biological membranes constitute boundaries of cells and cell organelles. Physico-chemical mechanisms at the atomic scale are dictated by protein-lipid interaction strength, lipid c…
Application of a Free Energy Landscape Approach to Study Tension Dependent Bilayer Tubulation Mediated by Curvature Inducing Proteins
Richard W. Tourdot, N. Ramakrishnan, Tobias Baumgart +1
We investigate the phenomenon of protein induced tubulation of lipid bilayer membranes within a continuum framework using Monte Carlo simulations coupled with the Widom insertion t…
