Polyelectrolyte-supported lipid membranes

In this work, we report the influence of the electrostatic interaction between lipid bilayer membranes and their solid polyelectrolyte multilayer support on the properties of the membrane. All involved sample preparation steps were carried out as convenient adsorption procedures from aqueous solutions. The lipid fluidity within the membrane as well as the surface coverage of the support could be tailored via the electrostatic interaction strength between the lipid bilayer and the supporting polyelectrolyte cushion.
