Biogenic synthesis and characterization of Silver nanoparticles from seed extract of Spondia mombins and screening of its antibacterial activity

The seed extract of Spondia mombins was used in the biofabrication of silver nanoparticles (AgNPs) in this study. The biosynthesized AgNPs was characterised using UV-Vis Spectroscopy, FTIR, FESEM, TEM, XRD and EDX. The antimicrobial efficacy of the synthetized AgNPs was evaluated against certain pathogens. The absorption spectrum peaked at ۴۲۵ nm when the UV analysis was carried out, with a large peak of ۳۰۰۰ to ۳۸۰۰ cm−۱ indicating different functional groups on the AgNPs surface when the FTIR analysis was conducted. An examination of FESEM and TEM showed a number of spherical particle structures ranging from ۱۰-۵۰ nm. XRD analysis also confirmed this size range. The AgNPs synthesized inhibited growth of the microorganisms used in this study. This study demonstrates that Spondia mombins’s seed extract has biomolecules that helped to bio reduce and stabilize the AgNPs synthesized, hence confirming the possibility of using Spondia mombins seeds in AgNPs synthesis.
