Lipid localization in bacterial cells through curvature-mediated microphase separation.

Although many proteins are known to localize in bacterial cells, for the most part our understanding of how such localization takes place is limited. Recent evidence that the phospholipid cardiolipin localizes to the poles of rod-shaped bacteria suggests that targeting of some proteins may rely on the heterogeneous distribution of membrane lipids. Membrane curvature has been proposed as a facto...

Microphase separation in nonequilibrium biomembranes.

Compositional heterogeneities of cell membranes are thought to play an important role in many physiological processes. We study how variations in the membrane composition can be driven by nonthermal fluctuating forces and therefore show how these can occur relatively far from any critical point for the membrane. We show that the membrane steady state is not only controlled by the strength of th...

Microphase separation in binary polymeric micelles

2014 A theoretical analysis of microphase separation in binary micelles is presented. We consider micelles consisting of two kinds of diblock copolymers such that the micellar corona contains two chemically distinct block types (A and B). Both intramicellar and intermicellar processes may occur. We focus on intermicellar segregation occurring after a quench yielding complete intramicellar micro...

Phase and microphase separation in polymer blends

When two different polymers are mixed, they usually demix because of the slight repulsive interaction that exists between their monomers. This is general and may be related to phase separation in two component mixtures. When the same polymer blend is cross-linked in the one phase region, elastic forces develop and do not let this to occur. There results a microphase separation, with coexistence...

Equilibrium microphase separation in the two-leaflet model of lipid membranes.

Because of the coupling between local lipid composition and the thickness of the membrane, microphase separation in two-component lipid membranes can take place; such effects may underlie the formation of equilibrium nanoscale rafts. Using a kinetic description, this phenomenon is analytically and numerically investigated. The phase diagram is constructed through the stability analysis for line...
