Copper Ferrite Nanoparticles: Structural, Magnetic, Optical, Photocatalytic Activity and Blood Compatibility Properties

In this study, CuFe2O4 nanoparticles (NPs) have been successfully synthesized via the co-precipitation method. Based on chemical composition and considering biological properties of CuFe2O4 ferrites nanoparticles, the structural, magnetic, photocatalytic and biocompatibility properties were investigated. X-ray diffraction analysis (XRD), scanning electron microscope (SEM), and UV–vis diffuse reflectance (DRS) spectrum techniques have been employed to analyze the structural and morphological properties of nanoparticles. By using the XRD results, it was found that the NPs have a cubic structure with a space group Fd3m. From UV–visible measurement, the direct and indirect gap energies of the Cu-ferrite NPs samples were obtained as 3.24 and 2.6 eV, respectively. Photocatalytic activity tests have showed that CuFe2O4 nanoparticles could degrade 55.4% of total organic dye after 1440 min of the model dye. Characteristics of the absorbance spectra obtained from hemolysis tests also revealed the possible interactions of copper and thiol (–SH) groups. Moreover, the observation of the formation of a characteristic black precipitate in hemolytic activity tests was interpreted as clear evidence for the formation of heme–iron complexes. The M-H loop shows a S-shaped pointing to the soft ferromagnetic behavior with the coercivity field (Hc) value of 1412 Oe, saturation magnetization (Ms) value of 14.06 emu/gr.
