Abstract

Targeted drug delivery is considered one of the most important biomedical application in the field of nanotechnology for the treatment of cancerous cells. Magnetic nanoparticles (MNPs) are widely used for targeted drug delivery due to their supermagnetic properties and biocompatibility. Because the vehicle has a strong magnetic moment, the drug can be released at any targeted location. Various factors such as temperature, pH, and applied magnetic field can be used for managing drug delivery. This chapter covers recent research into the use of MNPs in drug delivery and applications in areas such as stem cell therapy, pancreatic cell therapy, pulmonary drug delivery, gene delivery, and hydrogel delivery. Iron oxide is frequently used in drug delivery in the form of hybrid MNPs, magnetic biohybrid micromotors, and hollow mesoporous silica spheres, due to its special properties, which are also discussed in this chapter.
