Schematic representation of a magnetic nanoparticle-based drug delivery system. The steps for magnetic NP-based drug delivery are: Coupling the drug to the MNP; applying an external magnetic field to attract the MNP to the desired location, such as a tumor; and the release of the drugs from the NP under the influence of an external alternating magnetic field once it reaches the target. MNP = magnetic nanoparticle, NP = nanoparticle.
