(a) Ratio between the number of deposited PSS monomers and charges on the external leaflet of the liposome, Rc, for full charge overcompensation as a function of the weight fraction of DODAB in the liposomes. The labels “area” and “volume” refer to the two ways of calculating the number of charges in the outer layer of the liposome, and the results coincide. (b) Effect of the number of layers on the overcompensation ratio, Rc, of polyelectrolyte monomers on each layer for the deposition of a PSS/PAH onto DOPC:DODAB liposomes with a 70:30 compositional ratio. (c) Dependence of the zeta potential on the number of PSS/PAH layers adsorbed on the liposomes with different compositional ratios.
