Single source preparation of superparamagnetic Fe3O4 nanoparticles by simple cyclic microwave approach

- Superparamagnetic Fe3O4 nanoparticles were synthesized in high yield.
- PEG-200 was applied as both solvent and reductive agent.
- Single source synthesis of Fe3O4 was performed.
- Nontoxic materials and surfactant were used in current investigation.
- Reaction time and temperature significantly decreased in current experiment.
