Equilibrium Theory and Geometrical Constraint Equation for Two-Component Lipid Bilayer Vesicles

Towards two-component lipid bilayer membranes: snapping elastic curves

Studying a one-dimensional analogue of the spontaneous curvature model for twocomponent lipid bilayer membranes we consider planar curves that are made of a material with two phases. Each phase induces a different preferred curvature, and these curvatures as well as phase boundaries may cause the curves to develop kinks. We introduce a family of models for smooth curves and phase fields that ap...

Formation and properties of cell-size lipid bilayer vesicles.

Hydration of single or mixed phospholipids or lipid protein mixtures at low ionic strength results in the formation of a population of large, solvent free, single bilayer vesicles with included volumes of up to 300 microliters/mumol lipid. Their size ranges from 0.1 to 300 microns and they can be sorted out according to size by centrifugation. When formed in distilled water their internal solut...

Phase behavior of two-component lipid membranes: theory and experiments.

The structure of the ripple phase of phospholipid membranes remains poorly understood in spite of a large number of theoretical studies, with many experimentally established structural features of this phase unaccounted for. In this article we present a phenomenological theory of phase transitions in single- and two-component achiral lipid membranes in terms of two coupled order parameters: a s...

Rheological Behavior of a Dispersion of Small Lipid Bilayer Vesicles

Rheological behavior of a dispersion of small nearly-unilamellar phospholipid bilayer vesicles has been investigated. We conducted steady-state shear experiments and linear viscoelastic experiments. In the dilute and semidilute regime the rheological behavior is similar to that of a hard-sphere dispersion as reported in the literature for viscoelasticmeasurements, butnowalso observed in steady ...
