چکیده
|
In this study, at first, the biosynthesis of silver nanoparticles (ag nps) using an aqueous extract of thymbra spicatal was studied and then, the shape and size of synthesized nps were characterized by different analysis such as uvvis, tem, sem, edx, xrd, dls and ftir. the synthesized ag nps were evaluated for their antibacterial activity against escherichia coli (pttc 1707), staphylococcus aureus (pttc 1112), bacillus cereus (pttc 1154) and aspergillus niger (pttc 5012) and candida albicans (pttc5027) by well diffusion method and determination of minimum inhibitory concentration (mic). ag nps displayed significant antimicrobial activity against the specimens, and they prevented the growth of bacteria and fungi at low concentrations.
