Schematic representation of the 3 mechanisms used to load drugs in dendrimers: (1) through a covalent interaction between the drug to the periphery of the dendrimer; (2) by coordination of the drug to the outer functional groups of the dendrimer via ionic interactions; (3) by simple encapsulation of the drugs into the dendrimer cavities.
