Metal oxide nanoparticles, including Nano-silver, have antimicrobial effects against a wide range of microorganisms. The aim of this study was to investigate the effect of Nano-silver obtained from different parts of Saffron on Acinetobacter baumannii has always been identified as one of the most important nosocomial infections. In this study, saffron stigma, stamens, and petals were prepared, only stamens and petals caused the synthesis of Nano-silver. The diameter of Nanosilver was measured using TEM, then its effect on Acinetobacter baumannii was investigated by Disk and Well diffusion, MBC, and MIC methods. The results of the Disk diffusion method and the well diffusion method showed that with increasing the concentration of silver nanoparticles, the diameter of the bacterial growth aura increases. Also, the average MBC and MIC for saffron petal Nano-silver are 781 ppm and 390 ppm, respectively, and for saffron stamens Nano-silver, 3125 ppm, and 1562 ppm, respectively. It can be concluded that the petals and stamens of saffron reduce silver ions well and cause the synthesis of silver Nano-silver. The resulting Nano-silver also had a lethal effect on Acinetobacter baumannii. The abundance of saffron in Iran can be a good option for the production of Nano-silver.
