Figure 7: Liposome modulated for drug delivery. In this graphic representation, apart from the basic liposomal structure, one can also observe the protective polymers grafted to the lipid bilayer (upper left), peptides conjugated with lipids for directing the liposome to a certain target (right), a lipophilic molecule soluble in the lipid bilayer, and polar content soluble in the aqueous core.
