Green Synthesis and Characterization of Iron Nanoparticles from the Leaf Extract of Khaya senegalensis (Mahogany) and its Antimicrobial Activity

Abstract

The iron nanoparticles were green synthesized from the leaf extract of Khaya senegalensis, and ferric chloride (FeCl3) was utilized as a metal -precursor. The synthesized Nanoparticles were characterized using UV-Visible Spectophotomety, FTIR, SEM, and EDX and XRD. The UV-visible analysis results confirmed the formation of Nanoparticles. FTIR identifies the functional groups present, SEM coupled with EDX shows the morphology of (FeNPS) as spherical granular with no well-defined morphology. XRD analysis showed face-centered cubic (FCC) structures with an average particle size of 75.31nm. The FeNPS showed significant antibacterial and antifungal activities of the synthesized drugs (nanoparticles) when tested against Escherichia coli, Pseudomonas aeruginosa (Gram-negative), Staphylococcus aureus, Klebsiella pneumonia (Gram-positive) bacteria’s and two fungi Aspergillusniger and Candida—using augumentin and fulcin as control drugs.
