Summary : Lipid membranes have attracted much attention in the past decades, both for their unique physical properties, and for their wide biological relevance. For example, membranes are the main ingredient of cell walls, and stacks of lipid membranes play an important role as protective coatings in biolubrication systems and in the stratum corneum. Usually these biological systems are crowded, and membranes are confined between other membranes, or between other biological material.
In this talk, we will discuss the role of confinement on the adhesion of lipid membranes by studying the adhesion of a membrane between two flat walls within a hydrodynamic model. We find frozen states with finite-size adhesion patches, and an order-disorder transition controlled by the permeability of the walls. Adding noise to the model, we recover coarsening with exponents controlled by the wall permeability.
