“…Spinel ferrites have the general formula of “MFe 2 O 4 ” where “M” represents divalent cation (Zn, Cu, Mn, Co, Mg, Ni, etc.) 92 . Additionally, these NPs can be utilized for cellular labeling, hyperthermia, and anticancer applications.…”

Zn-doped CuFe2O4 nanoparticles (NPs) were eco-friendly synthesized using plant extract. These nanoparticles were characterized by X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy and thermal gravimetric analysis (TGA). SEM image showed spherical NPs with size range less than 30 nm. In the EDS diagram, the elements of zinc, copper, iron, and oxygen are shown. The cytotoxicity and anticancer properties of Zn-doped CuFe2O4 NPs were evaluated on macrophage normal cells and A549 lung cancer cells. The cytotoxic effects of Zn-doped CuFe2O4 and CuFe2O4 NPs on A549 cancer cell lines were analyzed. The Zn-doped CuFe2O4 and CuFe2O4 NPs demonstrated IC50 values 95.8 and 278.4 µg/mL on A549 cancer cell, respectively. Additionally, Zn-doped CuFe2O4 and CuFe2O4 NPs had IC80 values of 8.31 and 16.1 µg/mL on A549 cancer cell, respectively. Notably, doping Zn on CuFe2O4 NPs displayed better cytotoxic effects on A549 cancer cells compared with the CuFe2O4 NPs alone. Also spinel nanocrystals of Zn-doped CuFe2O4 (~ 13 nm) had a minimum toxicity (CC50 = 136.6 µg/mL) on macrophages J774 Cell Line.

“…One can be argued that all spectra consist of three magnetic sextets and one superparamagnetic doublet. One of the sextets is related to Fe 3+ ions at the tetrahedral A region while another sextets are associated with Fe 3+ ions at octahedral B region depending on the x value [45]. The existence of sextets points the magnetically aligned Fe atoms in the samples [62].…”

“…By modifying these parameters, the cobalt spinel ferrite can have low coercivity, least magnetic losses, enhanced saturation magnetization, narrow hysteresis curve. For examples, with the inclusion of non-magnetic elements [44,45], while the saturation magnetization (Ms) rises meanwhile the coercivity field (H c ) degrades [46][47][48][49]. Therefore, one of the effective ways to enhance the coercivity field is a non-magnetic rare Earth element substitution for cobalt ferrite.…”

In this research, the effect on the morphology, structure, optic, magnetic and Mossbauer features of Cu2+ doping in Co1-xCuxFe2O4 (x=0.0-1.0) nanoparticles fabricated using the sol-gel auto-combustion reaction method were investigated. The mainly pure phase structure of Co-spinel was observed in X-ray diffraction (XRD) patterns. The sizes of crystal were observed in between 28.77–36.25 nm. The fundamental vibrational bands of the nanoparticles have been found at 426 and 602 cm-1 wavelengths via the Fourier transform infrared (FT-IR) spectrum. The most of Co2+ ions are located at the A site and that substitution by Cu+2 ions at the octahedral site for x=0.0, 0.25, and 0.50. for x=0.75 content, the Mössbauer results show that some Cu2+ ions are present in both A and B sites. Magnetization measurements at room temperature show that Cu2+ substitution into Co-ferrite significantly changes the magnetic quantities such as coercivity field (Hc), remnant (Mr) and saturation magnetization (Ms). Magnetic hysteresis curves obtained at room temperature show well-known S-shaped features for all nanoparticles with Ms values of 51.5-64.4 emu/g, Mr values of 31-36 emu/g and Hc values of 429.5-1447.8 Oe.
