There are two strategies to load the chemical agent (i.e., the
drug) and magnetic particles onto dendrimers: encapsulation
and conjugation. In the process of encapsulation, drug
molecules are internalized by a carrier. Encapsulation involves
either hydrophobic interactions between the relatively nonpolar
cavities of dendrimers and the bonding between dendrimeric cavities and drug molecules.
Conjugation is a process of loading drug molecules onto the
surface of a carrier. It can be achieved via either covalent or
electrostatic interactions between the dendrimer and drug hydrophobic drug or hydrogen
