Effects of surfactants on the magnetic properties of iron oxide colloids

[Display omitted] •Superparamagnetic iron oxide nanoparticles with 9nm were produced.•Three different surfactants (oleic acid, sodium citrate, and Triton X-100) were tested.•Surfactants presence on the nanoparticles was confirmed by InfraRed analysis.•Oleic acid exhibits a good performance as stabil...
