Experimental and theoretical investigation of sugar-coated cobalt ferrite nanoparticles

In this work, the structural, magnetic, and toxicity properties of CoFe2O4@sugar nanoparticles synthesized via co-precipitation method were studied. X-ray diffraction (XRD) confirmed the cubic spinel structure of the sample, and scanning electron microscopy (SEM) was applied to investigate the morphology of them. The achieved results from Fourier transform-infrared spectroscopy (FT-IR), thermogravimetry analysis (TGA), vibrating sample magnetometer (VSM), and Monte Carlo (MC) simulation showed that the sugar molecules effectively interacted with the surface of the approximately single domain and non-interacting magnetic nanoparticles (MNPs) and reduced their coercivity (magnetic anisotropy). Moreover, the biochemical investigation on the laboratory animal revealed no significant toxicity.
