Magnetic Nanomedicine

Nanotechnology emerged as a promising field of science with a diversity of applications in energy storage, biotechnology, medicine, sensing, and healthcare monitoring and in each aspect of nature. Owing to the significant characteristics of the smaller size, easy modification, and tunable physical and chemical properties, magnetic nanomaterials have gained potential fame in the nanomedicine field. In terms of treatment and diagnosis, magnetic nanoparticles (MNP) cannot be replaced with any other material. Surface functionalization and coating of ferromagnetic and superparamagnetic nanoparticles not only make them biocompatible but also effective for drug delivery and killing tumor cells. In this book chapter, we highlighted the emerging applications of magnetic nanoparticles, from synthesis to potential applications. Specifically, brief introduction of magnetic nanomaterials and their physical properties is discussed in detail. Further, the facile synthesis methods to prepare MNPs and recent developments in MNPs as magnetic hyperthermia agents, as a drug transporter, and use in magnetic resonance imaging as a contrast agents are also elaborated profoundly.
