Optimizing Druggability through Liposomal Formulations: New Approaches to an Old Concept

Figure 6

When two or more liposomes come close enough, their lipidic membranes can interact in two different ways: they can either merge only with their outer lipid sheet (bottom left) or can fuse their entire membranes, essentially blending their contents (bottom right) [6].
