Self-assembled monolayers of Ag nanoparticles 7 nm in size, encapsulated by lipid molecules, are fabricated by using a solid-supported liquid-crystalline lipid membrane. By dissolving and reassembling these lipid-encapsulated Ag nanoparticles, various superstructures ranging from 2D planar superlattices and multistacked 3D superlattices to honeycomb-like structure are produced by varying the lipid concentration, temperature, and solvent.
