Abstract

A novel type of liposome, named here multivesicular liposomes, was prepared by evaporation of organic solvents from chloroform-ether spherules suspended in water. Within each spherule were numerous water droplets that contained solutes to be trapped in liposomes upon solvent evaporation. Liposome preparations of different average diameters were made, varying from 29 ± 10 μm to 5.6 ± 1.7 μm. The liposomes were morphologically characterized by light microscopy and transmission electron microscopy. Materials successfully trapped within the liposomes ranged in molecular size from glucose to nucleic acids. Extremely high percentages of encapsulation (up to 89%) were achieved.
