“…Moreover, core–shell structure of nanoparticles gained increasing attention in hyperthermia application . For example, Rashid et al prepared MgFe 2 O 4 /ZrO 2 composites for prevention of nanoparticles aggregation, for reduction of their dipolar interaction, and for enhancement of specific absorption rate and moreover ZrO 2 showed lower toxicity and higher bioavailability than iron oxides . Shaw et al synthesized IONPs doped by cerium for stabilization of temperature during hyperthermia, Dey et al invented novel synthesis method ferromagnetic cubic cobalt ferrite IONPs for simultaneous drug delivery with temperature‐sensitive release and for hyperthermia and Cruz et al obtained CoFe 2 O 4 and MnFe 2 O 4 nanoparticles with enhanced heating efficiency .…”

Although cancer is one of the most dangerous and the second most lethal disease in the world, current therapy including surgery, chemotherapy, radiotherapy, etc., is highly insufficient not in the view of therapy success rate or the amount of side effects. Accordingly, procedures with better outcomes are highly desirable. Iron oxide nanoparticles (IONPs) present an innovative tool-ideal for innovation and implementation into practice. This review is focused on summarizing some well-known facts about pharmacokinetics, toxicity, and the types of IONPs, and furthermore, provides a survey of their use in cancer diagnosis and therapy.

“…Hence, by combining ZrO 2 with narrow band gap semiconductor, photocatalytic activity can be enhanced. There are many reports available for the synthesis of NC with MnFe 2 O 4 for many applications such as MnFe 2 O 4 /rGO NC for ultra-stable supercapacitors [29], ZnO/MnFe 2 O 4 synthesis by organic-free media for dye degradation under natural sunlight [30], MnFe 2 O 4 /ZrO 2 by sol-gel method for sonocatalytic and photocatalytic degradation of methylene blue and methyl orange dye under UV-visible light [31], MnFe 2 O 4 /g-C 3 N 4 /TiO 2 NC generated by chemical impregnation method for degradation of methyl orange dye simulated under irradiation of solar light [32], magnetic microsphere MnFe 2 O 4 /polyaniline composite with electro-catalytic activity for oxygen reduction reaction [33] and MgFe 2 O 4 /ZrO 2 NC [34] by modified citrate gel method for hyperthermia applications.…”

Magnetically separable novel nano-MnFe 2 O 4 /ZrO 2 nanocomposite (NC) and MnFe 2 O 4 (MFO) samples were synthesized by an efficient solution combustion methodology. The structure, morphology and optical properties were characterized through powder X-ray diffraction, scanning electron microscopy, Fourier-transform infrared spectroscopy and UV-Vis spectroscopy. The photocatalytic activity of MnFe 2 O 4 /ZrO 2 nanocomposite was analysed for decolourization efficiency of methylene blue (MB) and textile dye wastewater under natural sunlight irradiation. The results demonstrated that the decolourization response of the MnFe 2 O 4 /ZrO 2 nanocomposite was 95% for MB and 59% for textile dye wastewater in 90 min. The photocatalytic performance of MnFe 2 O 4 /ZrO 2 was almost 1.4 times as high as pure MnFe 2 O 4 was ascribed to the synergic effect and interfacial interaction across MnFe 2 O 4 nanoparticle (NP) and ZrO 2 that leads to separation of electron-hole pairs efficiently and broadened light absorption of the composite (2.42 eV) compared to MnFe 2 O 4 (2.15 eV). The effective optimized parameters such as solution pH of 7, nanocomposite dosage of 60 mg and initial dye concentration of 20 ppm were studied on photocatalytic performance for the removal of MB dye. The magnetically separable MnFe 2 O 4 / ZrO 2 nanocomposite proved to be highly active and a stable catalyst in five successive photodecolourization cycles for an aqueous solution of MB dye under sunlight irradiation. Furthermore, the possible sunlight photocatalytic mechanism of the MnFe 2 O 4 /ZrO 2 nanocomposite was proposed. Due to its enhancement in photocatalytic activity, this NC has great potential towards the environmental remediation for practical photocatalytic application towards wastewater treatment.

“…Magnetically induced hyperthermia is proposed as an alternative anticancer therapy in which the heat produced by magnetic nanoparticles (MNPs) in radio frequency (RF) magnetic elds is used to destroy cancerous cells or retard their growth. [1][2][3][4][5][6][7][8][9][10][11] The therapeutic action is due to the magnetothermal effect by which MNPs transform alternate current (AC) magnetic eld energy into heat by different magnetic loss mechanisms, such as Néel and Brownian losses. 3 The heating efficiency of the MNPs is quantied in terms of the specic absorption rate (SAR), which is the amount of heat dissipated per unit time per unit mass of particles.…”
