green route of synthesis ag nps using reductant and stabilizer agent from plants extract as an efficient antibacterial and antifungal activity

Green, fast, and low-cost synthesis of ag nps were utilized at ambient temperature using extracts of plants (aloe vera and hibiscus sabdarriffa l.) as an eco-friendly reductant/stabilizer agent in the preparation of ag nps. xrd investigated the morphology, and the ag nps structure to determine the crystallinity, fs-sem to determine the morphologies, edx to determine the elemental composition and distribution, and uv-visible absorption spectrometer to understand the optical properties. primarily, the preparation of silver nps was observed by the change in color to dark- grey, and then confirmed by spr band at 431 nm using aloe vera leaf extract and at 410 nm using hibiscus sabdariffa flower extract in the analysis of uv-vis spectral. the significant peaks in the xrd pattern exhibited the fcc crystal structure of ag nps with particles size of 16.99 nm-26.99 nm from aloe vera leaf extract (and 13.11 nm-29.50 nm from hibiscus sabdariffa flower extract) are seen in fe-sem images. as a result, the synthesized ag nps using plant extract have a powerful antibacterial activity.
