The Role of Nickel Ferrite Magnetic Nanoparticles in Medical Science

The nanotechnology industry is accelerating day by day with its inspiring outcomes. These outcomes grease the wheels for smartening our world. This nanotechnology has immense range of applications in the field of aerospace engineering, nano-electronics, environmental remediation and medical healthcare. Nanoparticles are materials having overall size of less than 100 nanometers. These materials have become the key players in modern medicine in recent years, with therapeutic applications ranging from contrasts agents in imaging to medication and gene delivery carriers into malignancies. In some cases, nanoparticles make it possible to perform investigations and treatments which would otherwise be impossible. Nanoparticles, on the other hand, provide significant environmental and societal challenges, notably in terms of toxicity. This paper review will focus on nanoparticles major contributions to modern medicine, as well as their environmental and societal implications. In these fields, nickel ferrite nanoparticles play a very advantageous role when compared to other nanoparticles due to its typical physical, chemical and magnetic properties like high electrochemical stability, low conductivity and thus negligible eddy current loss, abundance in nature and the most important property of ferrite nanoparticles is the reduction in saturation magnetization (M_S) related to the bulk ferrite counterpart. The decrease in ?(M?_S) is linked to ins and outs, such as surface effects. This paper reviews mainly focuses on the structural behavior, magnetic properties, synthesis methods and concludes with some of its medical applications which includes hyperthermia, magnetic resonance imaging (MRI), magnetic separation and drug delivery of nickel ferrite nanoparticles.
