Multilaminar vesicles

Figure 11.14 (a) Chemical structures of polyfpropylene imine) dendrimers. (b) Illustration of the formation of the hilayer structure (1) injection of the dendrimer in an aqueous solution of pH < 8 (2) protonation of the nitrogen atoms (3) stmctural inversion of the dendrimer (4) self-aggregation of the protonated dendrimers to form multilaminar vesicles containing interdigitated bilayers.
