Silver nanoparticles (SNPs) were synthesised by using the Arial part extract of . and characterised by employing UV-visible spectroscopy, Fourier transform infrared spectroscopy and X-ray diffraction techniques. Transmission electron microscopy and field emission scanning electron microscopy were applied to investigate the morphological structure of the bio-synthesised SNPs. The antimicrobial activity of SNPs was studied against Gram positive ( and ) and Gram-negative ( and ) bacteria by employing the disk diffusion agar process. An extremely antimicrobial effect was observed for SNPs. Utilising as a mediator for the synthesis of SNPs helped to save time and cost.
