Abstract:
The hydrothermal approach is used in the current study to create an environmentally friendly
silver zinc oxide nanocomposite utilizing an aqueous leaf extract of Rumex Crispus. The photo chemical components of Rumex Crispus, a synthetic nanocomposite with antioxidant and anti bacterial activity, were also assessed. The Response Surface Methodology of Definitive Screen
Design (DSD) was used to examine and optimize the effects of four independent variables on the
amount of green synthesized silver zinc oxide nanocomposite in Rumex Crispus extract. Ac cording to the experimental findings, the green synthesized silver zinc oxide nanocomposite’s
maximum 1.89 absorbance intensity was achieved at a reaction temperature of 60 ◦C, a con centration of silver nitrate salt of 100 mM, a pH value of 11, and a reaction period of 3 h. The
synthesized nanocomposite was characterized using Fourier-transform infrared, UV, X-ray,
UV–vis, Dynamic Light Scattering, thermogravimetric analysis, and differential thermal analysis
to determine its functional group, structure, bandgap energy, size distribution, a mass of loss, and
energy gain or loss, respectively. The minimum lethal doses for the gram-positive, gram-negative,
and fungal strains were 1.25, 0.625, and 2.5 g ml− 1 respectively. The 1-1-diphenyl-2-picryl
hydrazyl (DPPH) which was used to measure antioxidant activity is scavenged by Ag–ZnO
nanocomposites, and the IC50 value of a Rumex Crispus extract is 29.31 g ml-1 IC50 value
is.29.31 μg ml– 1
. Their findings show that Rumex Crispus extract-derived synthetic silver zinc
oxide nanocomposite is a promising alternative against both Gram-positive and Gram-negative
bacterial strains and fungal strains, as well as a prospective choice for antioxidants under the
given conditions.
