Ordered-structures induced by electrostatic interaction in lipid bilayer membranes
One of our interest is to reveal the physical properties of lipid bilayer membranes containing charged phospholipids. We reported that the phase separation in charged lipid membranes is suppressed due to electrostatic repulsion between charged head groups experimentally and theoretically. Our goal is to construct the biomimetic system and understand the physico-chemical phenomena in such a system.
Line tension at phase-separated domain boundary
We investigate the specific pattern formation in lipid membranes by controlling the line tension at phase-separated domain boundary.
Dynamical behavior of lipid membrane by coarse-grained molecular dynamics simulation
Our aim is to understand the dyanmical behavior of the lipid membranes using coarse-grained molecular dynamics simulation.
