Elastic Properties and Line Tension of Self-Assembled Bilayer Membranes ELASTIC PROPERTIES AND LINE TENSION OF SELF-ASSEMBLED BILAYER MEMBRANES
The bending moduli and line tension of bilayer membranes self-assembled from diblock copolymers was calculated using the self-consistent field theory. The limitation of the linear elasticity theory (Helfrich model) was evaluated by calculating fourthorder curvature moduli in high curvature systems. It was found that in highly curved membranes, the fourth-order contributions to the bending energ...
متن کاملShape fluctuations and elastic properties of two-component bilayer membranes
– The elastic properties of two-component bilayer membranes are studied using a coarse grain model for amphiphilic molecules. The two species of amphiphiles considered here differ only in their length. Molecular Dynamics simulations are performed in order to analyze the shape fluctuations of the two-component bilayer membranes and to determine their bending rigidity. Both the bending rigidity a...
متن کاملElastic properties and line tension of self-assembled bilayer membranes.
The elastic properties of a self-assembled bilayer membrane are studied using the self-consistent field theory, applied to a model system composed of flexible amphiphilic chains dissolved in hydrophilic polymeric solvents. Examining the free energy of bilayer membranes with different geometries allows us to calculate their bending modulus, Gaussian modulus, two fourth-order membrane moduli, and...
متن کاملFrom Polymers to Membranes: Elastic Properties of Red Blood Cells
Recently experiments have been conducted to investigate the behavior of live human red blood cells under optical forces generated using both linearly and circularly polarized light [1, 2]. These experiments have shown that a normal human RBC, which has a biconcave disk shape, approximately 8 μm in diameter, deforms into a folded shape upon being placed in an optical trap; the trapped RBC subseq...
متن کاملElastic membranes in confinement.
An elastic membrane stretched between two walls takes a shape defined by its length and the volume of fluid it encloses. Many biological structures, such as cells, mitochondria and coiled DNA, have fine internal structure in which a membrane (or elastic member) is geometrically 'confined' by another object. Here, the two-dimensional shape of an elastic membrane in a 'confining' box is studied b...
