The influence of structural properties on antibacterial potential of Mg0.95Fe0.03O nanoparticles

Magnesium ferrite nanoparticles (Mg₀.₉₇Fe₀.₀₃O) were synthesized using the sol-gel method to investigate their structural, optical, and antibacterial properties. The study aims to explore the effect of Fe doping on MgO nanoparticles and their efficiency as antibacterial agents. X-ray diffraction (XRD) confirmed the crystalline structure, with the crystallite size calculated to be 10.88 nm. UV-Vis spectroscopy revealed an optical bandgap (Eg) of 3.32 eV, indicative of the material\'s semiconducting nature. The antibacterial activity of Mg₀.₉₇Fe₀.₀₃O nanoparticles was evaluated against Staphylococcus aureus, demonstrating a zone of inhibition (ZOI) of 15 mm. The results suggest that Fe doping enhances both the structural stability and antibacterial efficiency of MgO nanoparticles, making them suitable for applications in biomedicine and environmental remediation. This study highlights the potential of Mg₀.₉₇Fe₀.₀₃O nanoparticles as multifunctional materials with promising properties for various industrial and healthcare applications.
