Embedding and self-organization of nanoparticles in phospholipid multilayers.
Multilayers of various phospholipids on silicon substrates are used to induce spontaneous embedding of nanoparticles deposited from the gas phase. The resulting nanoparticle arrangement on the substrate surface is characterized using at. force and SEM. In the intermediate phase and the liq. cryst. phase of the lipid, a monolayer is formed around individual nanoparticles which leads to an increase in interparticle distances. At the same time, the mol. mobility of the multilayers allows for self-assembly of the particles in regular two-dimensional arrangements.
