An Overview on Synthesis and Applications of Iron Oxide Nanoparticles

Abstract

Iron oxide nanoparticles especially magnetite and maghemite find various applications in the biomedical as well as engineering field due to its biocompatibility and non toxic nature. There are various applications especially in the field of biomedicine. Due to the wide applications of iron oxide nanoparticles its demand in various fields is increasing considerably. In this review, we have made an attempt to present an overview of the synthesis methods and applications of iron oxide nanoparticles. They are used in the biomedical field as contrast agents in MRI, for targeted drug delivery, hyperthermia etc.Magnetic nanoparticles are of great importance due to its unique magnetic property in the nanoregime. They exhibit superparamagnetic behavior that is they are magnetic only in the presence of magnetic field, which makes it a suitable candidate for research now and then. Also among all magnetic nanoparticles, magnetite and maghemite gain special attention because of its biocompatibility and non-toxic nature. Hence here a discussion is focusedabout the properties to be satisfied by iron oxide nanoparticles to be used for various applications.
