the obtained results indicate that the particle size was in a range of 17-30 nm and of a circular shape. The proper chitosan covering was also indicated by FTIR results. The VSM analysis also revealed that the saturated magnetization of NiFe 2 O 4 nanoparticles stood in a range of 29 emu/g and 45 Q e . A stable maximum temperature ranging from 30 to 42 was successfully achieved within 10 min. Also, a specific absorption rate of up to 8.4 W/g was achieved. The study results revealed that the SAR parameter of the coated nickel ferrite nanoparticle is more than that of pure nickel ferrite or cobalt ferrite nanoparticles.

“…Magnetite/gold core-shell NPs have many advantages due to their low toxicity, plasmonic, and superparamagnetic nature [15,16]. Although various magneto-plasmonic NPs ranging in their morphology, size, and shape have been reported, such as gold and silver shells with a magnetite core [17], magnetite-gold nanoshells [18], dumbbell magnetite/gold NPs [19], and core-satellite magnetite/gold NPs [20], the most prominent core-shell shape consists in a concentric spherical one, which allows altering the core nanoparticle surface with another material, without compromising their properties. However, the synthetic routes present some disadvantages, promoting the formation of a magnetite-Au NPs composite rather than a core-shell structure [21].…”

Magnetite/gold core-shell nanoparticles (magnetite/gold NPs) have important optical and magnetic properties that provide potential for applications, especially biomedical ones. However, their preparation is not exempt from difficulties that might lead to unexpected or undesired structures. This work reports the synthesis and characterization of magnetite/gold NPs using tetramethylammonium hydroxide (TMAH) to promote the formation of a continuous interface between the magnetite core and the thin gold shell. The synthesized magnetite/gold NPs were characterized using transmission electron microscopy (TEM), energy-dispersive spectroscopy (EDS), field emission scanning electron microscope (FE-SEM), ζ-potential, vibrating sample magnetometer (VSM), selected area electron diffraction (SAED), UV-Visible spectroscopy, and dynamic light scattering (DLS), confirming the core-shell structure of the NPs with narrow size distribution while evidencing its plasmonic and superparamagnetic properties as well. Further, the magnetite/gold NPs were associated and stabilized with a β-cyclodextrin nanosponge (β-CDNSs), obtaining a versatile magneto-plasmonic system for potential applications in the encapsulation and controlled release of drugs.
