“…Heating efficiencies may go much higher in the future since techniques for controlling these particles' size composition, shape, and size have not yet been completely developed as they have for iron oxides [18]. The sol-gel synthesis of cobalt-copper ferrite nanoparticles was investigated for their potential to induce magnetic hyperthermia [19]. The optimum temperature was achieved using copper-substituted CoFe 2 O 4 nanoparticles coated with chitosan for magnetic fluid hyperthermia [20].…”

The wide variety of uses for nanoparticles (NPs) is due to their unique combination of features in a single assembly. The arc melted copper-cobalt ingot sample were qualitatively studied using laser induced breakdown spectroscopy (LIBS). Later, using the fabricated alloy as a target material for Nd:YAG laser ablation, CuCo2O4 NPs were synthesized. The magnetic properties of the synthesized NPs were studied using a vibrating sample magnetometer (VSM). To determine the composition and morphology of the synthesized NPs, X-ray diffraction (XRD), energy dispersive X-ray (EDX) analysis, transmission electron microscopy (TEM), scanning electron microscopy (SEM), and dynamic light scattering (DLS) techniques were used. The TEM and DLS showed that particles were spherical in shape with an average size of 32 nm and 28 nm, respectively. The antibacterial activity of the synthesized NPs was studied against S. aureus and E. coli strains as positive and negative controls using a standard approach. CuCo2O4 nanoparticles exhibited non-mutagenic potential against S. typhimurium TA-98 and TA-100 strains. Furthermore, the magnetic hyperthermia study of CuCo2O4 nanofluid was examined using a lab-made apparatus. The specific absorption rates (SAR) of 4.57 and 5.17 W/g were determined for the magnetic field strength of 230 μT and 247 μT, respectively. The study shows antibacterial activity and magnetic hyperthermia potential of the synthesized nanoparticles.

Magnetic nanoparticles (MNP) are anticipated to perform better in terms of thermal conductivity when exposed to alternating magnetic fields (AMF). Herein, key parameters for efficient heating are examined in an AMF that is organized and managed by a zero voltage switching (ZVS) and frequency counter system, which has shown great potential for hyperthermia (HT). The present study investigates the set-up of a matched coil coupled with direct current (DC) power and a frequency counter. The set-up technique for inducing HT in magnetic fluid NPs used in in vitro experiments and magnetic fluid calorimetric applications is advanced. Superparamagnetic iron oxide nanoparticles Fe3O4 (SPIONs) was prepared by the sonochemical method and coated with polyethylene glycol (Fe3O4@PEG). Our sample Fe3O4@PEG crystallized nano-size with an average particle size of 14 nm, and high magnetic saturation (MS) about 49 emu/g. The MNPs exposed to AMF at 300 kHz exhibited the highest thermal values (42–45 °C). The specific absorption rate values of 188, 217, and 234 W/g for the NP concentrations of 5, 10, and 20 mg/ml, respectively reveal the improvement of our set-up to enhance the SPIONs as a thermal agent.
