Green Synthesis of Ag-Fe Bimetalic Nanoparticle from Mahogany Leaf (Khaya Senegalensis) Extract and its Antimicrobial Applications

Abstract

Researchers from all over the world have become increasingly concerned about bimetallic nanoparticles in recent years. In particular,  these hybrid species are quite attractive for some technological purposes, particularly in the study of antibiotics. This study used a green  method to create Ag–Fe bimetallic nanoparticles from khaya seneglences leaf extract, which were then characterized using variety of methods, such as UV, FT-IR, SEM, magnetic susceptibility and EDX. The UV results of Ag–Fe bimetallic nanoparticles displayed a distinctive  UV–Vis spectrum, with the wavelength of 400 nm corresponding to the maximum absorbance peak at 0.375. The FT-IR bands that were  detected were 872.19705 cm⁻¹, 1021.29057 cm⁻¹, 1408.93370 cm⁻¹, 1565.48189 cm⁻¹, 2952.0516 cm⁻¹, and 3369.51340 cm⁻¹. The EDX  analysis affirms that Ag and Fe nanoparticles were formed because their respective peaks show up at 68.24 concentration (Ag) and 12.39  concentration, respectively. Effective antibacterial activity against pathogenic bacteria was shown by the antimicrobial research of Ag-Fe Bimetallic Nanoparticles made from khaya seneglences extract. Pseudomonas aeroginosa showed a larger zone of inhibition for every  concentration examined than other pathogens. On the basis of complex, F.W (g/mol), Phase State, Shape, and Color, a few physical  characteristics of the particle were also established. The complex, which is paramagnetic by nature, was also subjected to a magnetic suspectibility test. The solubility test was tested using four different solvents, DMSO, water, peptone, and ethanol, with DMSO being  shown to be the most appropriate solvent.
