Physicochemical characterization of the different nanoparticles used. A TEM images of the iron oxide nanoparticles used, scale bar: 20–50 nm. B Nanoparticle size distribution and Gaussian fitting. C Magnetization curve at RT for the IONPs showing their superparamagnetic behavior. D Data related to iron leaching from the iron oxide under the specified conditions (pH 7 or 5), depending on the size and on the type of coating
