Green Synthesis of Gold Nanoparticles using Extract of Vitis vinifera, Buchananialanzan, Juglandaceae, Phoenix Dactylifera Plants, and Evaluation of Antimicrobial Activity

The establishment of nanotechnology, nanoparticles from gold (Au-NPs) is one of the extensive attention due to its essential properties. In this study, the green synthesis of gold NPs from the extract of Raisins, Charoli (Buchananialanzan), Walnut (Juglandaceae), and Black dates (Phoenix dactylifera) plants is reported. While all the (bark)show FCC face-centered cube structure as FCC as permitted reflection is (111), (200), (220), (311), the gold particles either show the cubic structure or face center cubic structure. The FT-IR spectra show the presence of natural products with functional groups hydroxyl, amine, amide, acid, and ester, respectively. The antimicrobial activity shows that the NPD3 shows well to moderate antimicrobial activity with S. aureus, E. coli, B. subtilis, and P. aeruginosa organisms. The NPD3 at 50 mg/mL concentration shows the 12mm, 11mm, 14m, and 14mm zone of inhibition.
