dc.description.abstract[Hypothesis]: Superparamagnetic MnxFe3-xO4 nanoparticles are promising materials for applications in biomedicine and other fields. Small variations in the Mn/Fe ratio have a strong impact on the properties of the nanoparticles. Those variations may be caused by the synthesis itself and by common post-synthesis manipulations like surface modification.es_ES
dc.description.abstract[Experiments]: Mn-ferrite nanoparticles have been prepared changing systematically the Mn/Fe ratio of the metal precursors and repeating each reaction three times. Nanoparticles were subjected to surface modification with two different and typical molecules to stabilize them in aqueous media. The discrepancy in the Mn/Fe ratios of the precursors with the ones measured after the synthesis and the surface modification have been studied, as well as its impact on the saturation magnetization, blocking temperature, contrast enhancement for magnetic resonance imaging, magnetic heating, and on the cytotoxicity.es_ES
dc.description.abstract[Findings]: Mn is incorporated in the nanoparticles in a relatively lower amount than Fe and, as this report shows for the first time, both Mn and Fe ions leach out from the nanoparticles during the surface modification step. The blocking temperature decreases exponentially as the Mn/Fe ratio increases. The transverse and longitudinal relaxation times and the magnetic heating ability change appreciably even with small variations in the composition.es_ES
