Multifunctional Magnetic Nanomaterials for Diverse Applications

Multifunctional nanostructures have been at the center of attention in nanoscience and technology based on their enhanced functionality and diverse applicability in a plethora of devices. Fusing two distinctly different properties in a single nanostructure provides plenty of opportunities to tune these nanomaterials for diverse applications. Of these usage of multifunctional nanomaterials in biomedical fields have been on the rise since their multiple functionalities can be utilized for diagnosis, therapeutic, targeting uses as well as increasing cellular uptake with proper functionalization. In this chapter we will discuss about some multifunctional magnetic nanostructure, especially focusing on the Au-Fe3O4 nanostructures and their potential application biomedical fields. The catalytic uses of these nanostructures for water oxidation reaction has been also discussed with the multifunctional iron oxides as well as the metal selenide nanostructures.
