Manganese ferrite nanoparticles were synthesizedusing a High-Energy Ball-Milling mechanochemicalmethod. After 1 h of milling, the processproduces a material consisting of single crystallinedomain nanoparticles having a diameter of about8 nm. Chemical properties of the synthesized powdersallow an easy functionalization with citric acid. Bothas-obtained and functionalized samples show superparamagneticbehaviour at room temperature, and thefunctionalized powder is stably dispersible in aqueousmedia at physiological pH. The average hydrodynamicdiameter is equal to *60 nm. Nanoparticlesobtained by the reported High-Energy Ball-Millingmethod can be synthesized with high yield and lowcosts and can be successfully utilized in ferrofluidsdevelopment for biomedical applications.
