“…The synthesis process used herein is a modified version of a previously reported co-precipitation method [14,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35]. The molar ratio of iron(III) chloride hexahydrate(8.1 g): iron(II) chloride tetrahydrate (3.97 g): cobalt(II) chloride hexahydrate (2.37 g) was precisely set to be 3:2:1 and mixed in 50 mL of distilled water for 15 min to obtain a homogeneous solution at room temperature.…”

“…Cobalt ferrite nanoparticles have been prepared by several methods, including sol-gel [11], hydrothermal [12,13], co-precipitation [14], and thermal decomposition methods [15,16]. Using the co-precipitation process, many researchers have made efforts to achieve the smallest possible particles and to improve the magnetic properties and SLP of the cobalt ferrite nanoparticles and cobalt zinc ferrite nanoparticles [14,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35]. The ferromagnetic-superparamagnetic size threshold for cobalt ferrite nanoparticles has been reported by Pereira et al, who prepared superparamagnetic cobalt ferrite nanoparticles with the tuning of particle size (4.2−4.8 nm) and magnetic properties ( M s 30.6–48.8 emu/g) using a co-precipitation method.…”

“…Saturation magnetization increases with the increase in particle size until it reaches a threshold size beyond which magnetization is constant and is close to the bulk value [23]. Recently, a high SLP of 237–272 W/g metal was obtained with CoFe 2 O 4 nanoparticles via the co-precipitation method at 90 °C in the presence of chitosan as a coating agent [17]. In another report, a high SLP of 91.84 W/g metal was obtained using CoFe 2 O 4 nanoparticles via a co-precipitation method, at room temperature in the presence of a coating agent (polyethylene glycol and oleic acid) [18].…”

Magnetic nanoparticles (MNPs) that exhibit high specific loss power (SLP) at lower metal content are highly desirable for hyperthermia applications. The conventional co-precipitation process has been widely employed for the synthesis of magnetic nanoparticles. However, their hyperthermia performance is often insufficient, which is considered as the main challenge to the development of practicable cancer treatments. In particular, ferrite MNPs have unique properties, such as a strong magnetocrystalline anisotropy, high coercivity, and moderate saturation magnetization, however their hyperthermia performance needs to be further improved. In this study, cobalt ferrite (CoFe2O4) and zinc cobalt ferrite nanoparticles (ZnCoFe2O4) were prepared to achieve high SLP values by modifying the conventional co-precipitation method. Our modified method, which allows for precursor material compositions (molar ratio of Fe+3:Fe+2:Co+2/Zn+2 of 3:2:1), is a simple, environmentally friendly, and low temperature process carried out in air at a maximum temperature of 60 °C, without the need for oxidizing or coating agents. The particles produced were characterized using multiple techniques, such as X-ray diffraction (XRD), dynamic light scattering (DLS), transmission electron microscopy (TEM), ultraviolet-visible spectroscopy (UV–Vis spectroscopy), and a vibrating sample magnetometer (VSM). SLP values of the prepared nanoparticles were carefully evaluated as a function of time, magnetic field strength (30, 40, and 50 kA m−1), and the viscosity of the medium (water and glycerol), and compared to commercial magnetic nanoparticle materials under the same conditions. The cytotoxicity of the prepared nanoparticles by in vitro culture with NIH-3T3 fibroblasts exhibited good cytocompatibility up to 0.5 mg/mL. The safety limit of magnetic field parameters for SLP was tested. It did not exceed the 5 × 109 Am−1 s−1 threshold. A saturation temperature of 45 °C could be achieved. These nanoparticles, with minimal metal content, can ideally be used for in vivo hyperthermia applications, such as cancer treatments.

“…There are reported studies about maghemite stabilized by calcium silicate, [71] magnesium, [72] silica, [73] dextran, starch, poly(ethylene glycol), polyethylenimine, poly(vinyl alcohol), poly(acrylamides), poly(lysine), and chitosan [60] in the literature. Another group of well‐known hyperthermic agents is based on ferrites, such as cobalt ferrite, [74] manganese ferrite, [74b,75] nickel ferrite, [74b] zinc ferrite [76] and some mixed ferrites like Co 1−x Mn x Fe 2 O 4 , [77] Ni 1‐x Zn x Fe 2 O 4 , [78] Zn 1−x Ca x Fe 2 O 4 , [79] Zn x Mn y Fe z O 4 and Zn x Co y Fe z O 4 [80] . Iron oxides are favored because of their biodegradable nature, biocompatibility, and superparamagnetic effects.…”

Hyperthermia generates heat as a cure for illness and it is not a chemical treatment. Nanomaterials are supposed to provide novel mechanisms to tackle photothermal and magnetothermal problems, with the potential also to deal with specific approaches to care. The present review outlines recent developments in the field of photothermal and magnetothermal responsive nanomaterials and the photothermal approach mechanism over the last years. These photo/magnetothermal nanomaterials are classified into gold nanostructures (various shapes), carbon nanomaterials (CNTs, fullerene, carbon quantum dots, and graphene), inorganic nanomaterials (Fe, Pt, Pd, Bi, MOF, MoSe2, inorganic quantum dots, etc.) and organic nanoparticles (PLGA (Poly Lactic‐co‐Glycolic Acid) and other nanopolymers). Different groups may be placed together to improve the potential of the photothermal/magnetothermal effects, treatments, drug delivery, and imaging. The review also describes synthesis strategies for photothermal/magnetothermal nanomaterials, physicochemical characterization, the role of size, size distribution, shape, and surface coating of nanomaterials, challenges, and future scopes of photothermal/magnetothermal responsive nanomaterials for therapy, controlled drug delivery, and imaging applications. The recent development in nanomaterial has shown great potential for tumor diagnostic and therapeutic applications in hyperthermia. Magnetic hyperthermia (also called thermal therapy or thermotherapy) is a type of cancer treatment in which body tissue is exposed to high temperatures (up to 41 °C) in presence of a magnetic field. Research has shown that high temperatures can damage and kill cancer cells, usually with minimal injury to normal tissues. By killing cancer cells and damaging proteins and structures within cells, hyperthermia can necrotize tumor cells. This treatment can be local, regional, or whole‐body hyperthermia, depending on the extent of the area being treated. Hyperthermia can be combined with anticancer drugs or chemotherapy to enhance cancer treatment. In this article, we have discussed recent nanomaterials utilized for this treatment, mechanism, and synthesis methods.

“…To overcome this problem, the biocompatible surface-coating (i.e. chitosan) helps to stabilize the ferrite NPs and provides an available surface area for the biomolecular conjugation for biomedical applications [51]. In this regard, the study of the effect of chitosancoated Co 1−x Mn x Fe 2 O 4 (x = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0) NPs obtained via wet chemical co-precipitation on the hyperthermia temperature (directly related to specific loss power for cancer treatment) revealed that Co 0.2 Mn 0.8 Fe 2 O 4 exhibited hyperthermia range [52].…”

Engineered nanomaterials with tailored properties are highly required in a wide range of industrial fields. Consequently, the researches dedicated to the identification of new applications for existing materials and to the development of novel promising materials and cost effective, eco-friendly synthesis methods gained considerable attention in the last years. Cobalt ferrite is one of the nanomaterials with a wide application range due to its unique properties such as high electrical resistivity, negligible eddy current loss, moderate saturation magnetization, chemical and thermal stability, high Curie temperature and high mechanical hardness. Moreover, its structural, magnetic and electrical properties can be tailored by the selection of preparation route, chemical composition, dopant ions and thermal treatment. This chapter presents the recent applications of nanosized cobalt ferrites doped or co-doped with divalent transition ions such as Zn 2+ , Cu 2+ , Mn 2+ , Ni 2+ , Cd 2+ obtained by various synthesis methods in ceramics, medicine, catalysis, electronics and communications.
