چکیده

Synthesis of silver nanoparticles using seeds of Nigella sativa as reducing agent was evaluated in this study. Homogenized extract of N. sativa exposed to sunlight gave a better synthesis of nanoparticles when compared to other methods. Antibacterial activity of nanoparticles was studied against urinary tract infection (UTI) causing bacteria by disc diffusion method. Further, the silver nanoparticles were characterized by UV, XRD, FTIR, SEM and EDAX. The findings suggest that silver nanoparticles from seeds of N. sativa may be effectively used against UTI causing bacteria.
