Characterization and antibacterial activity of biogenic iron nanoparticles using Proteus mirabilis

Abstract

Background:The green production of iron oxide nanoparticles (FeONPs) due to its numerous biotechnological uses has attracted a lot of attention and clean and eco-friendly approaches in the medical field.Objectives:The objectives of this study are to demonstrate the biogenic creation of FeONPs. The search for alternative antimicrobial medicines has been prompted by growing worries about multidrug resistance.Materials and Methods:The purpose of this work was to investigate if Proteus mirabilis was the source of green-manufactured iron nanoparticles (INPs). The Fourier transform infrared, attenuated total reflectance, scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray spectroscopy, ultraviolet–visible, and dynamic light scattering measurements were used to characterize the green synthesized nanoparticles (NPs). Using the agar-well diffusion method, the antibacterial investigation’s efficacy was evaluated.Results:The results found that at 128 μg/mL minimum inhibitory concentration, we have demonstrated the potent antibacterial properties of FeONPs produced through biological procedures against Gram-positive and Gram-negative bacteria that are resistant to many drugs. These NPs, including their antimicrobial qualities, how they work, how they affect drug-resistant microbes, the risks involved with using them, the unique qualities of NPs, their mode of action as antibacterial properties, and the elements that influence how well they function in a therapeutic setting all are thoroughly investigated.Conclusion:Further research on biogenic INPs was necessary to enhance their nanopharmacological importance for biological applications, as they have demonstrated promising biomedical capabilities were successfully synthesized in a friendly environment with few costs, and the highly INPs product showed exceptional activity against bacterial strains.
