  A method for preparing lipid vesicles having suitable size for drug delivery (in a few hundred nanometer size) with high entrapment efficiency of hydrophilic molecules was developed. The lipid vesicles containing hydrophilic molecules in their internal compartments were formed from water-in-oil-in-water (W1/O/W2) multiple emulsions after the removal of organic solvent by evaporation under ambient condition. The primary W1/O emulsions were formed via homogenization by sonication of mixture of oil phase containing bilayer forming lipids, and the water phase containing hydrophilic molecules to be entrapped. The W1/O/W2 multiple emulsions were formed through microchannel (MC) emulsification by introducing the dispersed phase, i.e., (W1/O) emulsion, into the MC device in the presence of polymeric surfactants in the external water phase. The average size of the lipid vesicles formed, measur.. Read More»
