• Fe3O4 nanoparticle
• solventless synthesis
• size control

The novel synthesis of monodisperse magnetite Fe3O4 nanoparticles of varying sizes using a solventless synthetic method was developed. Iron salt was treated in excess oleylamine and oleic acid as ligands. The effect of the reaction temperature and time on the particle size was investigated and the particle sizes were easily tuned from 5.3 to 20.4 nm by changing the reaction temperature and time.
