Abstract:

ent study has been designed to synthesis silver nanoparticles (SNPs) and Copper nanoparticles (CuNPs) using leaf aqueous extracts of Cadaba fruticosa an endangered medicinal plant as bioreducing agents. This method authorized the synthesis of SNPs, which was authenticated by Ultraviolet (UV)-visible Spectrophotometry, Fourier-transform infrared analysis, X-ray Diffraction (XRD) studies, Energy Dispersive X-ray, and Scanning Electron Microscopic (SEM) analysis. UV-visible spectra and visual observation exhibited the appearance of greenish brown and dark brown color indicates the synthesis of SNP and CuNP, after the treatment of Ag precursors. Further the, XRD report clearly shows that the synthesized SNPs were crystalline in nature. In addition, SEM analysis confirmed that AgNO3 solution produced SNPs and CuO2 solution produced CuNPs and their size was about 120–168 nm and 301–538 nm in SNPs and CuNPs, respectively. The leaf SNPs and CuNPs of C. fruticosa leaf aqueous extracts considerable antioxidant activities. The results antimicrobial activity exhibited that the bacterial and fungal growth was inhibited by both the samples in a dose-dependent manner.
