Abstract
The spreading kinetics of dimyristoylphosphatidylcholine liposomes at the air/water interface, below and above the main phase-transition tem perature are studied by measuring the evolution of the surface pressur e. The reorganization mechanism of the closed liposomal bilayers into a surface film is dependent on the state of the bilayer. The estimated values of the interfacial reorganization rate constant for liposomes in a liquid-crystal state are larger than those for liposomes in cryst al-gel state. Atomic force microscopic imaging demonstrates the differ ent morphology of the interfacial mesophases obtained.
