Characterization and Antibacterial Activity of Silver Nanoparticles Biosynthesized Using Leaves Extract of Artemisia sieberi and Calotropis procera

The prevalence of antibiotic-resistant bacteria has increased recently leading to the need for novel, natural antibacterial agents such as plant-synthesized silver nanoparticles. Such synthesis is safe, cheap, rapid, non-toxic and environmentally friendly. In this study, characterization biosynthesized nanoparticles from extracts A. sieberi C. procera was carried out using transmission electron microscopy, fourier transform infrared energy dispersive x-ray analysis. Spherical with an average size ~10 nm ~14 were synthesised; most effective sieberi. Antibacterial activity agar-diffusion method by determination minimum inhibitory concentration. Biosynthesized showed against Staphylococcus aureus, MRSA, Salmonella typhimurium Escherichia coli, being antibacterial.
