Dynamics of phospholipid aggregation in ethanol--water solutions

The kinetics of liposome and vesicle formation of a synthetic lecithin has been studied by light scattering techniques. It is shown, that by evaporation of alcohol from a lipid--alcohol--water mixture, the aggregates formed undergo several changes in shape. A hypothesis is presented, visualising the formation of liposomes or vesicles from monomers, which is consistent with the experimental observations.
