Surface-engineered Multimodal Magnetic Nanoparticles: Scope and Applications

Magnetic nanoparticles (MNPs) are one of the classes of nanoparticles that produce magnetic properties by manipulation using a magnetic field. These MNPs are currently used in the theranostics disease modification of surface properties of MNPs, achieved by surface engineering, which provides different applications, such as enhancing thermal and optical properties, biocompatibility, conductivity and also mechanical and chemical properties. Advancement in the technology leads to the development of MNPs. For this instance, surface coating is used at molecular and cellular levels. The uses of coating material are based on organic and inorganic molecules, including polymer, liposomes, micelles, metal oxide, gold-NPs etc. Using different coatings exhibits multifunction properties, and this helps reduce toxicity, helps in biomedical applications, maintains stability, restricts surface fouling, etc. This review provides an in-depth knowledge of surface-engineered magnetic nanoparticles (MNPs) according to recent developments.
