Abstract
A lipid vesicle comprising a phospholipid which is a stable vesicle former and at least one unstable vesicle forming member, wherein the unstable vesicle forming member is selected from the group consisting of a polar lipid which is not a stable vesicle former, a PEG, a raft former and a fusion protein is provided. The vesicle can further comprise a biomolecule, such as for example ATP. Methods of using the vesicle for delivery of biomolecules are also provided.
