Probing lipid membrane bending mechanics using gold nanorod tracking
Mehdi Molaei, Sreeja Kutti Kandy, Zachary T. Graber +3
Lipid bilayer membranes undergo rapid bending undulations with wavelengths from tens of nanometers to tens of microns due to thermal fluctuations. Here, we probe such undulations a…
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…
Curvature-driven migration of colloids on lipid bilayers
Ningwei Li, Nima Sharifi-Mood, Fuquan Tu +4
Colloids and proteins alike can bind to lipid bilayers and move laterally in these two-dimensional fluids. Inspired by proteins that generate membrane curvature, sense the underlyi…
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…
