Bimetallic nickel-ferrite nanorod particles: greener synthesis using rosemary and its biomedical efficiency

Abstract

Nickel-ferrite (NiFe 2 O 4) nanorods particles (NRP) was biosynthesised for the first time by the Rosemary Extract. The NRP was fully characterised, including the type, nanostructure and physicochemical properties of using XRD, HRTEM, FeSEM, XPS, FTIR and VSM. TEM confirmed rod-shaped nano-sized particles with average sizes ranging from 10 nm to 28 nm. The EDAX Analysis showed the presence of iron, nickel, oxygen, and carbon. XRD analysis confirmed the synthesis of NiFe 2 O 4 crystals. XPS curves showed photoelectron for iron, oxygen and nickel. EDS showed the atomic, weight percentages ratios of Ni(12%): Fe(24%) and: O(48) are close to the theoretical value (Ni: Fe:O ¼ 1:2:4), of bimetallic magnetic NiFe 2 O 4 NRP. NiFe 2 O 4 NRP had cytotoxicity effect on MCF-7 cells survival which suggests that NiFe 2 O 4 NRP can be used as a new class of anticancer agent in design novel cancer therapy research.

Cytotoxicity evaluation of environmentally friendly synthesis Copper/Zinc bimetallic nanoparticles on MCF-7 cancer cells

“…Nanomaterials are one of the promising areas of medical research and have been used to diagnostic and treatment of many dangerous diseases, including COVID-19 (Tang et al 2021 ). Among the types of nanoparticles, bimetallic nanostructure from the combination of two different metals have unique properties in the field of light, heat, catalytic, drug delivery and therapeutic effects (Alijani et al 2020 ). The physical and chemical properties of bimetallic and tri-metal nanoparticles are different from the properties of individual metals due to the compositions and interactions between the individual components of these nanostructures (Khatami et al 2018 ; Wang et al 2018 ).…”

Observation of Spin-Glass-like Behavior over a Wide Temperature Range in Single-Domain Nickel-Substituted Cobalt Ferrite Nanoparticles

“…The primary goal of this research was to optimize the hydrothermal recipe for making single-domain monodispersed ferrite nanoparticles, as well as to characterize their structural, morphological, and magnetic properties. Understanding the magnetic characteristics of these stable ferrite nanoparticles and having a reproducible recipe for producing them in the single-domain regime is essential for using them in a variety of applications, including magnetic devices, chemical sensors, and biomedical applications [ 4 , 17 ].…”

“…The resulting nanostructures were separated through centrifuging, and then were washed with ethanol-deionized water and deionized water. Finally, these nanostructures were dried for 16 h at 60 degrees Celsius in an electric oven and ground into a soft powder 59 .…”
