Magnetic Microspheres for Targeting of Drugs
The particles should be small enough to remain in the circulation after injection (i.e. ∅ <2–3 μm).
The magnetic material should be non-toxic.
The polymer should be biocompatible, i.e. non-toxic and non-immunogenic.
The polymer should allow binding of drugs by covalent attachment, adsorption or entrapment.
