Magnetic Nanoparticles; Synthesis, Properties and Electrochemical Application: A Review

Background: The Fe3O4 nanoparticles have been highly regarded in recent years due to their unique properties and different applications. Magnetic separation capability of Fe3O4 nanoparticles provides an environmentally friendly procedure for the synthesis of this nanoparticle and its derivatives. Objective: There are many methods for synthesizing magnetic nanoparticles, and the properties of these nanoparticles are largely dependent on their synthesis method. Magnetite has many applications in various fields, one of the most important of which is the application of electrochemical sensors. These nanoparticles attached to the surface of different electrodes and used for the sensitive and selective electrochemical determination of trace amounts of several combinations. In this review paper, recently suggested synthesis methods of Fe3O4 and its derivatives and their electrochemical application are discussed.
