Background: In the last decade, Fe3O4 nanoparticles have been intensively investigated for medical applications. Up now, various chemical methods have been applied for their preparation. Although, these methods have been improved in the recent years, however, higher temperature (100-300 oC), toxic and expensive precursors and limited controllability of particle morphology and size still the challenges. As an alternative method, cathodic electrochemical deposition can be effectively applied for the preparation of metal oxides and hydroxides nanoparticles. However, this electrochemical route has been rarely applied into the synthesis of iron oxide nanoparticles, and surface coating of these NPs has not been reported through this method.
