Monodisperse polyelectrolyte-supported asymmetric lipid-bilayer vesicles

Abstract

Assymetric lipid-bilayer vesicles based on monodisperse polyelectrolyte (PE) were fabricated using LbL-colloid templating. It was observed that the diameters of the PE supported lipid bilayer vesicles corresponded closely to t hose the the original template particles. The assymetry retained by the lipid bilayers was due to their complexation with the PE support. The results show that the complexation also enhances the bilayer morphological stability against surfactants.
