This volume covers current research in the usage of magnetic nanoparticles for drug delivery. It discusses synthesis methods, stabilizers used for surface coating on MNPs, and potential target ligands which can be used to ferry payloads to the targeted disease region. It also highlights the factors affecting delivery efficiency and toxicity, as well as the different routes of administration. The content also focus on the use of these carriers for gene therapy and to target brain tumors. This volume will be of interest to researchers working on drug discovery and delivery platforms.
