Abstract
A novel encapsulation method is provided in which liposome dispersions are dried in the presence of a material to be encapsulated. As drying occurs, the individual liposomes fuse to form multilamellar structures which capture the material between lipid lamellae. Upon rehydration, lipid vesicles form which efficiently encapsulate the material.
