Abstract

Understanding the interactions of nanoparticles with lipid membranes is crucial in establishing the mechanisms that govern assembly of membrane-based nanocomposites, nanotoxicology, and biomimetic inspired self-assembly. In this study, we explore binding of charged nanoparticles to lipid bilayers, both as liposomes and substrate supported assemblies. We find that the presence of a solid-support, regardless of curvature, eliminates the ability of zwitterionic fluid phase lipids to bind charged nanoparticles.
