Abstract

The aim of this study was to evaluate the antibacterial and antifungal activities of eco-friendly synthesized silver nanoparticles. The silver nanoparticles were synthesized by biological method using aqueous extract of Abronia villosa. Synthesis of silver nanoparticles was confirmed by color change and characterized using UV-visible spectroscopy, scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX), dynamic light scattering (DLS), and zeta potential analysis. The SEM analysis revealed the presence of spherical silver nanoparticles of the size range 21 to 33 nm. Synthesized silver nanoparticles were used to evaluate their antibacterial effects at different concentrations (25, 50, 75 and 100 µg/ml) on gram negative and gram positive bacteria. The biggest halo zone was observed at 75 and 100 µg/ml concentrations of silver nanoparticles against both gram positive and gram negative bacteria. Antifungal activity of biosynthesized silver nanoparticles was evaluated against seven different phytopathogenic fungi. AgNPs showed high inhibition of radial growth toward all tested fungi. The highest inhibition of fungal growth by AgNPs was recorded against Macrophomina phaseolina (86.06 ± 0.92%). Biosynthesized AgNPs using plant extract are a promising to use safety for various biomedical and agricultural applications.
