“…Among these ferrite NPs, CoFe 2 O 4 is recognized for its significant chemical stability, high Curie temperature, and high magnetization [7, 8]. Studies on such materials involved analysis of the effect of Gd doping on the structural and magnetic properties of CoFe 2 O 4 synthesized through wet chemical co-precipitation method [7].…”

The effect of Zn-doping in CoFe2O4 nanoparticles (NPs) through chemical co-precipitation route was investigated in term of structural, optical, and magnetic properties. Both XRD and FTIR analyses confirm the formation of cubic spinel phase, where the crystallite size changes with Zn content from 46 to 77 nm. The Scherrer method, Williamson-Hall (W-H) analysis, and size-strain plot method (SSPM) were used to study of crystallite sizes. The TEM results were in good agreement with the results of the SSP method. SEM observations reveal agglomeration of fine spherical-like particles. The optical band gap energy determined from diffuse reflectance spectroscopy (DRS) varies increases from 1.17 to 1.3 eV. Magnetization field loops reveal a ferromagnetic behavior with lower hysteresis loop for higher Zn content. The magnetic properties are remarkably influenced with Zn doping; saturation magnetization (Ms) increases then decreases while both coercivity (HC) and remanent magnetization (Mr) decrease continuously, which was associated with preferential site occupancy and the change in particle size.

“…From Table 1 , the averaged crystallite size of the MnFe 2 O 4 ferrite nanoparticles at various SDS concentrations decreases with increasing SDS concentration from 10.6 nm to 7.80 nm. This is because the surfactant influences the particle–particle interaction at the nano-scale; the higher surfactant concentration corresponds to the weaker particle–particle interaction, and the crystallite size is reduced [ 30 ]. The averaged crystallite size of Fe (1−x) Mn x Fe 2 O 4 _1.2CMC_SDS increases with increasing Fe 2+ cation substitution (with x = 1 to 0) from 7.80 nm to 13.3 nm, as the increase in Fe 2+ ions substitution increases the crystal growth rate, leading to the crystallite size enlargement [ 46 ].…”

“…The individual particle size decreases with increasing SDS surfactant concentration, consistent with the decreasing crystallite size in Table 1 . Adding the SDS surfactant reduces the crystallite and particle sizes as the SDS micelles disrupt the particle–particle interaction and the crystal growth rate [ 21 , 30 , 44 , 49 ]. For the MnFe 2 O 4 _1.0CMC_SDS and Fe (1−x) Mn x Fe 2 O 4 _1.2CMC_SDS, the aggregated particle sizes (d’) are 49 ± 8 nm and 40 ± 8 nm, respectively.…”

“…Recently, a cobalt ferrite nanoparticle (CoFe 2 O 4 ) was synthesized by the co-precipitation method at various cetyltrimethylammonium bromide (CTAB) concentrations. The aggregation decreased with increasing CTAB surfactant [ 30 ]. Furthermore, the substitution at the tetrahedral with different divalent cations led to the changes in the magnetic properties.…”

Manganese ferrite nanoparticles (MnFe2O4) were synthesized via surfactant-assisted co-precipitation, where sodium dodecyl sulfate (SDS) was used as the template to control particle size at various SDS concentrations. The substitutions of iron (II) (Fe2+) into the MnFe2O4 ferrite nanoparticles were carried out to obtain Fe(1–x)MnxFe2O4, with various Mn2+: Fe2+ molar ratios. The synthesized ferrite nanoparticles were characterized by the Fourier-transform infrared spectroscopy (FT-IR), thermogravimetric analyzer (TGA), X-ray diffractometer (XRD), energy dispersive X-ray (EDX), X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), transmission electron microscope (TEM), two-point probe, and vibrating sample magnetometer (VSM) techniques. The experimental Mn:Fe mole ratios of the Fe(1−x)MnxFe2O4 ferrite nanoparticles were verified to be in agreement with the theoretical values. The synthesized MnFe2O4 and Fe(1−x)MnxFe2O4 ferrite nanoparticles were of mixed spinel structures, with average spherical particle sizes between 17–22 nm, whereas the magnetite ferrite nanoparticles (Fe3O4) were of the inverse spinel structure. They showed soft ferromagnetic behavior. The synthesized Fe0.8Mn0.2Fe2O4 ferrite nanoparticle possessed the highest saturation magnetization of 88 emu/g relative to previously reported work to date.

Nanotechnology is a multidisciplinary branch of science which encompasses numerous diverse fields of science and technology, ranging from biomedical, pharmaceutical, agricultural, environmental, advanced materials, chemical science, physics, electronics, information technology, and so on. Physical and Chemical properties as a major advantages of Nanoparticles can be used in various applications from Industries to medicine. Besides, Magnetic nanoparticles for medical applications have been developed by many researchers. In recent decades, it has received attention by virtue of their potential for applications in different fields. Due to several advantages and widespread applications of magnetic Nanoparticles in biotechnology, medical, material science, engineering, and environmental areas, much attention has been paid to the synthesis of different kinds of Biomagnetic nanoparticles (BMNPs). Core-shell nanoparticles include of coated various materials like: biopolymers (Chitosan, PAA) and bioceramics (Hydroxyapatite) as a shell on top of them and different hard and soft materials like metal oxide (Iron oxide and Cob alt composite) as a core. Improved properties of core-shell nanoparticles like less cytotoxicity, increase biocompatibility, decrease in an interactions with biomolecules, increase physicochemical stability and sort of that, can be due to their use in biological applications. After reviewing several research and review articles and synthesis procedure of Iron based Bio-magnetic Nanoparticles (BMNPs), we should emphasize that, It can be used in different applications like magnetic resonance imaging (MRI), drug delivery systems (DDS), immunoassay, also specially in diagnosis and treatment of cancer via hyperthermia (heat therapy) method.
