Bilayer membrane.

Dynamics of Bilayer Membrane

The theory combines the Rouse model for a single chain with the liquid crystal theory for bilayer membrane developed by Marcelja. Thus the forces acting on a bead within a chain are spring forces, Brownian force and dissipative or viscous force which appear in Rousetheory plus the liquid crystal and lateral pressure forces. The dynamic viscosity of the system is calculated. 1 . Introduction. Ex...

Wrinkling of a bilayer membrane.

The buckling of elastic bodies is a common phenomenon in the mechanics of solids. Wrinkling of membranes can often be interpreted as buckling under constraints that prohibit large-amplitude deformation. We present a combination of analytic calculations, experiments, and simulations to understand wrinkling patterns generated in a bilayer membrane. The model membrane is composed of a flexible sph...

Polyethylene Glycol Repairs Damaged Membrane; Biophysical Application of Artificial Planar Bilayer to Mimic Biological Membrane

Polyethylene glycol (PEG) is a hydrophilic polymer, known to be capable to fuse numerous single cells in vitro, to join the membranes of adjacent neurons and giant invertebrate axons, and to seal damaged neural membranes. The molecular mechanism of the action of PEG is still unknown. It is believed that PEG dehydrates membranes and enables their structural components to resolve and rearrange in...

Membrane Electrochemistry: Electrochemical Processes in Bilayer Lipid Membrane

Dynamics of bilayer membranes. 1. Isolated membrane

Phenomenological studies of lipid bilayer membranes have become imperative, for a large amount of experiments reveal that the matrix of biomembrane plays an important role in some non-linear phenomena such as shape fluctuations of cells and oscillations of the membrane potential in an external electric field (1-3). In approaching the problem, however, one is immediately confronted with complexi...
