dc.description.abstractLight-transmitting measurements of white light and a consequentially chosen laser beam of 655 nm propagatingthrough citrate- and oleate-coated CoFe2O4, FeFe2O4, and MgFe2O4 nanoparticles under the influence of anexternal magnetic field were presented. New experimental settings were developed for the optical study offerrites’ behavior in ferrofluid with the applied magnetic field strength within the 30–400 mT range. A magneticfield-induced change of light transmittance occurred and a precipitation of all studied samples was obtained.Optical investigations of ferrofluid suspensions revealed that, contrary to the linear aggregates of colloidalCoFe2O4 and FeFe2O4, spheroidal aggregates were formed in the case of MgFe2O4. In all three cases, the surfacemodification resulted in decreased dipole–dipole interactions between ferrite cores, and thus, less precipitateswere noticed. All oleate-coated nanoparticles have demonstrated weaker magnetic responses compared to thecitrate-encapsulated samples. The aggregation of nanoparticles potentially increases cytotoxicity. Regardingnon-linear clustering of MgFe2O4 suspensions, it can be concluded that its excretion from the organism maylikely be easier and faster when used in diagnosis and/or therapy. Therefore, more attention should be paid tothe lowly toxic MgFe2O4 regarding its medical application.en
