Exploring NiFe2O4 nanoparticles: Electrochemical analysis and evaluation of cytotoxic effects on normal human dermal fibroblasts (HDF) and mouse melanoma (B16-F10) cell lines

Nanobiotechnology facilitates the development of novel materials with potential applications in human health, the environment, and a variety of industries. We used X-ray diffraction (XRD) to characterize NiFe2O4 nanoparticles (NPs), confirming a cubic crystal structure with crystallite sizes of 19 nm and 21 nm. Synthesized NPs spherical shape morphology was confirmed by field emission-scanning electron microscopy (FE-SEM) and an average diameter (prepared NPs) of 20 nm and 23 nm was revealed by Transmission electron microscopy (TEM). The chemical state was determined using X-ray photoelectron spectroscopy (XPS). A vibrating sample magnetometer (VSM) was used to measure the magnetic characteristics. The electrochemical characteristics of prepared electrodes could be useful for supercapacitor applications. Changing the surfactants, reaction temperature, and heating duration considerably enhanced electrochemical performance, according to our findings. At 700 degrees C, specific capacitance (Cs) attained an outstanding value of 67.2 F/g. The prepared NPs cytotoxicity was performed on normal human dermal fibroblast (HDF) and mouse melanoma (B16-F10) cell lines. The current findings show that these NPs are non-toxic at concentrations ranging from 0 to 1000 mu g/mL. These findings point to prospective biomedical uses for NiFe2O4 NPs.
