Physical aspects of heterogeneities in multi-component lipid membranes

S Komura, D Andelman - Advances in colloid and interface science, 2014 - Elsevier
Ever since the raft model for biomembranes has been proposed, the traditional view of
biomembranes based on the fluid-mosaic model has been altered. In the raft model …

Line active molecules promote inhomogeneous structures in membranes: theory, simulations and experiments

B Palmieri, T Yamamoto, RC Brewster… - Advances in colloid and …, 2014 - Elsevier
We review recent theoretical efforts that predict how line-active molecules can promote
lateral heterogeneities (or domains) in model membranes. This fundamental understanding …

Hydrodynamic lift of a two-dimensional liquid domain with odd viscosity

Y Hosaka, S Komura, D Andelman - Physical Review E, 2021 - APS
We discuss hydrodynamic forces acting on a two-dimensional liquid domain that moves
laterally within a supported fluid membrane in the presence of odd viscosity. Since active …

Concentration fluctuations and phase transitions in coupled modulated bilayers

Y Hirose, S Komura, D Andelman - … Review E—Statistical, Nonlinear, and Soft …, 2012 - APS
We consider the formation of finite-size domains in lipid bilayers consisting of saturated and
hybrid lipids. First, we describe a monolayer model that includes a coupling between a …

Lateral diffusion induced by active proteins in a biomembrane

Y Hosaka, K Yasuda, R Okamoto, S Komura - Physical Review E, 2017 - APS
We discuss the hydrodynamic collective effects due to active protein molecules that are
immersed in lipid bilayer membranes and modeled as stochastic force dipoles. We …

Diffusion coefficient of an inclusion in a liquid membrane supported by a solvent of arbitrary thickness

K Seki, S Ramachandran, S Komura - … E—Statistical, Nonlinear, and Soft Matter …, 2011 - APS
The diffusion coefficient of an inclusion in a liquid membrane is investigated by taking into
account the interaction between membranes and bulk solvents of arbitrary thickness. As …

Relaxation dynamics of two-component fluid bilayer membranes

R Okamoto, Y Kanemori, S Komura… - The European Physical …, 2016 - Springer
We theoretically investigate the relaxation dynamics of a nearly flat binary lipid bilayer
membrane by taking into account the membrane tension, hydrodynamics of the surrounding …

Anomalous lateral diffusion in a viscous membrane surrounded by viscoelastic media

S Komura, S Ramachandran, K Seki - Europhysics Letters, 2012 - iopscience.iop.org
We investigate the lateral dynamics in a purely viscous lipid membrane surrounded by
viscoelastic media such as polymeric solutions. We first obtain the generalized frequency …

Hybrid lipids increase nanoscale fluctuation lifetimes in mixed membranes

B Palmieri, SA Safran - Physical Review E—Statistical, Nonlinear, and Soft …, 2013 - APS
A recently proposed ternary mixture model is used to predict fluctuation domain lifetimes in
the one phase region. The membrane is made of saturated, unsaturated, and hybrid lipids …

Drag coefficient of a raftlike domain embedded in a fluid membrane being a near-critical binary mixture

Y Fujitani - Journal of the Physical Society of Japan, 2013 - journals.jps.jp
We consider a circular liquid domain in a flat fluid membrane surrounded by three-
dimensional fluids, and assume that the membrane outside the domain is a two-dimensional …
