Multifunctional Magnetic Nanomaterials

Magnetic nanomaterials are the category of nanomaterials that capable to be influenced externally with controllable size and, in the presence of magnetic field. The magnetic nanomaterials are in focus of most of the research recently because of the potential benefits exhibited by these materials. In this paper the applications of magnetic nanomaterials such as biomedicine (tissue specific targeting), cell tracking, drug delivery, medical imaging, protein purification, waste water treatment, genetic engineering, data storage, etc. are discussed. The paper also gives an exposure to various magnetic nanomaterials and theoretical views of magnetism on nanomaterials, some ideas as future prospects are proposed based on the applications and the materials discussed.
