“…A high SAR value indicates the requirement of less amount of the sample for hyperthermia treatment. This leads to quick biodegradation of NPs in living organs . It is noticed that the particles synthesized using the hydrothermal method produced a lower SAR value than the sol–gel method.…”

“…Thus, a body temperature range of 40 to 44 °C is said to be cytotoxic for normal cells and is called hyperthermia . These studies reveal that hyperthermia therapy can be used as an independent therapy, similar to industry standard radiation therapy, chemotherapy, and immunotherapy for cancer treatment. , In conventional whole-body hyperthermia and regional hyperthermia techniques (ultrasonic, capacitive, and inductive techniques), the body around the tumor is used to heat and this heating is nonhomogeneous . The precision and efficiency of hyperthermia treatment can be increased by a localized heating .…”

Magnetic hyperthermia is an emerging technique used for the treatment of tumors, where the infected cells will be deactivated using the heat generated from magnetic particles. This study discusses the viability of yttrium iron garnet (YIG) in magnetic hyperthermia treatment. YIG is synthesized using hybrid microwaveassisted hydrothermal and sol−gel auto combustion techniques. The formation of the garnet phase is confirmed using powder X-ray diffraction studies. Further, the morphology and grain size of the material are analyzed and estimated with the help of field emission scanning electron microscopy. Transmittance and optical band gap are obtained using UV−visible spectroscopy. Raman scattering of the material is discussed to understand the phase and vibrational modes. The functional groups of garnet are studied using Fourier transform infrared spectroscopy. Further, the effect of the synthesizing routes on the characteristics of the materials is discussed. A relatively higher magnetic saturation value is observed in the hysteresis loop at room temperature of YIG samples, which is synthesized by a sol−gel auto combustion technique, and it confirms the ferromagnetic behavior. The colloidal stability and surface charge of the prepared YIG are evaluated by a zeta potential measurement. In addition, magnetic induction heating studies are carried out for both prepared samples. The specific absorption rates of 1 mg/mL concentration are 237 and 214 W/g at 35.33 kA/m and 316 kHz field of sol−gel auto combustion and hydrothermal methods, respectively. Due to their higher saturation magnetization of 26.39 emu/g, the sol−gel auto combustion method produced effective YIG and demonstrated superior heating efficiency than the hydrothermally prepared sample. The prepared YIG are biocompatible, and their hyperthermia properties may be explored in various biomedical applications.

“…Heating the tumor cells leads to their necrosis or apoptosis in the magnetic fluid hyperthermia method [16,17]. Some parameters affect the results of killing cells in this method such as nanoparticle diameter, types of coatings of MNPs, aggregation of nanoparticles in magnetic fluid, and material used in the synthesis of MNPs.…”

In this study, a more precise and cost-effective method is used for studying the drug delivery and distribution of magnetic nanoparticles in fluid hyperthermia cancer treatment, and numerical methods are employed to determine the effect of blood circulation on heat transfer and estimate the success of cancer treatment. A combination of numerical, analytical, and experimental researches is being conducted, which illustrates the essential role of numerical methods in medical and biomedical science. Magnetic NanoParticles' distribution and effects of infusion rate on the treatment are also discussed by considering the real distribution of MNPs. To increase accuracy and reduce costs in the in-vitro section, direct cutting and image processing methods are used instead of MRI. Based on the results of this section, with a tenfold increase in the infusion rate (4 μl/ min to 40 μl/min), the penetration depth increases by 1 mm, which represents a nearly 17 percent increase. Concentrations of MNPs also decrease significantly at higher infusion rates. The simulations of heat transfer reveal that maximum temperatures occur at the lowest infusion rate (1.25 μl/min), and blood flow also has a significant effect on heat transfer. With an increase in the infusion rate, necrosis tissue recedes from the tumor center and approaches the border between the tumor and healthy tissue. Results also show that, in lower MNPs' concentrations, higher infusion rates result in better treatment even though minimum infusion rates are suggested to be the best rates to facilitate distribution and treatment.
