Self-assembly of iron oxide nanoparticles mediated by phospholipids

A monolayer of 7-nm-sized Fe 3 O 4 nanoparticles produced by spin-coating the Fe 3 O 4 nanoparticle suspension containing phospholipid molecules. It was demonstrated that the Fe 3 O 4 nanoparticles can be self-assembled into a 2D superlattice mediated by a liquid-crystalline phospholipids.
