Abstract

In this paper, we report for the first time the use of onion Allium cepa in the biosynthesis of silver nanoparticles AgNPs under microwave irradiation. Influence of various reaction parameters such as microwave irradiation power and microwave irradiation time was analyzed. The synthesized nanomaterial was characterized by UV-visible absorption spectroscopy and Fourier transform infrared spectrum analysis. X-ray diffraction XRD and transmission electron microscopy TEM confirm the formation and the crystalline nature of the synthesized nanomaterial. Further, these nanoparticles were found to exhibit high antibacterial activity against two different strains of bacteria Escherichia coli Gram negative and Staphylococcus aureus Gram positive.
