Sensitive MnFe₂O₄–Ag hybrid nanoparticles with photothermal and magnetothermal properties for hyperthermia applications

Abstract

In this study, we present an experiment showing that designing multifunctional MnFe2O4–Ag nanoparticles to act as a dual hyperthermia agent is an efficient route for enhancing their heating ability.

Synthesis and Antibacterial Activity of Manganese-Ferrite/Silver Nanocomposite Combined with Two Essential Oils

“…According to the results of the characterization and TEM images shown in Figure 1, the average size of the MnFe 2 O 4 -NPs and the MnFe 2 O 4 /Ag-NC was ~3 nm and ~14 nm, respectively. The coprecipitation method also resulted in an increase in the size of MnFe 2 O 4 -Ag hybrid nanoparticles, as reported by Nha et al [10]. However, the in situ biogenic reduction with G. officinalis used in this study may have added other elements behaving as stabilizing agents, leading to a larger size of the MnFe 2 O 4 /Ag-NC.…”

“…This is a valuable strategy for recycling magnetic nanoparticles and silver-magnetic nanocomposites from an aqueous medium that can minimize the environmental release of silver [8,9]. Other advantages of using MnFe 2 O 4 -NPs include their stability in air and high magnetic saturation relative to other magnetic materials [10]. In this context, nanocomposites based on MnFe 2 O 4 -NPs and silver have been mainly studied for environmental applications due to their ability to decompose dyes in water resources, as well as to adsorb contaminants [11][12][13].…”

Synthesis of Multifunctional Eu(III) Complex Doped Fe3O4/Au Nanocomposite for Dual Photo-Magnetic Hyperthermia and Fluorescence Bioimaging

“…C is the specific heat capacity of water (4.185 J g −1 K −1 ), m is the concentration (mg mL −1 ) of the FOASET nanoparticles in the solution, and dT/dt is the slope of the measured heating curve [ 18 ].…”

“…Some functional materials, such as silica, polymers, plasmon noble metals (gold, silver, etc. ), and luminescent materials, have been coated and combined with magnetic nanomaterials to improve the heating efficiency, improve biocompatibility, and expand their applicability towards theranostics [ 14 , 15 , 16 , 17 , 18 , 19 , 20 ].…”
