The importance of different polymorphic forms of iron oxide nanoparticles attracted a lot of attentions in various applications due to their unique electrical, optical and magnetic properties. Moreover, the excellent biocompatibility, high surface area, spherical shape, tunable nanoscale size and the availability of synthesis route make them desirable in various biological and pharmaceutical applications. To this aim, in this review, different synthesis methods of iron oxide nanoparticles were discussed, also the main characterization techniques used for elucidation of the iron oxide nanoparticles were reviewed. The exploitation of iron oxide nanoparticles-based systems as anticancer, antiviral, antimicrobial agents and its involvement in drug delivery system were reviewed in details. Additionally, the influence of nanoparticles size and the reagent type and conditions utilized in synthesis and their pharmaceutical applications was highlighted.
