Abstract
- Monodisperse cobalt ferrite (CoFe2O4) nanoparticles were prepared with various additions of polyvinylpyrrolidone (PVP) by a facile sonochemical method.
- PVP-coated CoFe2O4 showed relatively well dispersion and homogeneous shape with narrow size distribution.
- PVP-coated CoFe2O4 exhibited superparamagnetism with moderate saturation magnetization and hydrophilic character at room temperature.
- Negligible cytotoxicity of PVP-coated CoFe2O4 was observed even at high sample concentration after 24Â h treatment.
