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.
