Asymmetric lipid bilayer sandwiched in polyelectrolyte multilayer films through layer-by-layer assembly

Lipid bilayer of 1,2-dimyristoyl-sn-glycero-3-phosphoethanolamine (DMPE) was formed on the surface of a linearly growing polyanion/polycation polyelectrolyte multilayer (PEM) film prepared by the layer-by-layer (LbL) technique. The PEM films were prepared with two strong polyelectrolytes—poly(sodium 4-styrenesulfonate) (PSS) as the polyanion and poly-(diallyldimethylammonium chloride) (PDADMAC) as the polycation. The DMPE was always deposited...
