The prepared biogenic nanoparticles were well characterized using U.V. visible spectroscopy, scanning electron microscopy, X-ray diffraction and Fourier-transform infrared spectroscopy. The particles were confirmed to be elemental crystal by X-ray diffraction. <span style="mso-bidi-font-size:9.0pt;letter-spacing: -.1pt" lang="EN-GB">The <span style="mso-bidi-font-size:9.0pt; letter-spacing:-.1pt" lang="EN-GB">potential applications of biosynthesized nanoparticles as antimicrobial (antibacterial and antifungal) against pathogens Escherichia coli, Vibrio cholerae, Aspergillus niger and Aspergillus flavus were demonstrated. </span
