Magnetic Nanoparticles and Its Biomedical Applications

Magnetic nanoparticles (MNPs) gained a significant attention in biomedical research due to their precise functions and physical properties at bio-interface areas such as drug delivery, tissue engineering and lab‐on‐a‐chip. The functionalization plays a vital role in the manufacture of multifunctional MNPs with extensive therapeutic and diagnostic capabilities. Due to their exclusive properties like biocompatibility and targeting, MNPs have become an essential research area in the field of nano-medicine. Superparamagnetic nanoparticles have the properties that permit them to be focussed around the body with a magnetic field, which opens up the prospective to conjugate numerous biomolecules to these nanoparticles that could then be applicable in the field of gene therapy. With the aggregate superiority of pharmaceuticals, the histrionic progress of cell management and even DNA sequencing increases the possibility of using MNPs to expand its effectiveness along with new-generation technology in the field of biomedical applications. MNPs can be reduced by three orders of magnitude, and its size is analogous to the size of genes, proteins and micro-organisms, that can offer attractive possibilities for biomedical applications. Magnetic NPs reveal specific properties in the field of biophysical chemistry making them a useful tool for both therapy and medical diagnostics.In this chapter, we focus on the application of MNPs in the biomedical field, an outlook of the future developments in the use of magnetic NPs for advanced biomedical applications are critically provided. In order to translate the properties of magnetic nanoparticles into various biomedical application level in clinical as well as industrial sceneries, the challenges in the diverse measurements also be addressed.
