Biosysnthesis, Characterization And Antimicrobial Activities Of Zinc Oxide Nanoparticles From Leaf Extract Of Acmella Oleracea

The potential for the synthesis of metallic and semiconductor nanoparticles has expanded research applications in the development of novel technologies. In the present study, a simple and eco-friendly package. Zinc oxide nanoparticles (ZnO NPs) use Acmella oleracea leaf extract. ZnO NPs are characterized by various techniques such as UV-Vis , XRD, DLS, FE-SEM , EDX and FT-IR. XRD data showed the crystallinity of nanoparticles and EDX measurements indicates higher zinc content 67.63% and 32.37% of oxygen. FT-IR confirmed the presence of functional groups of leaf extract and ZnO NPs. DLS results confirmed successful synthesis of ZnO nanoparticles. Size and morphology of particles determined from FE-SEM and UV visible absorption spectra ZnO NPs exhibited absorption band at 314 nm. Combined ZnO nanoparticles are potentially antibacterial agents have been studied in Enterococcus aerogenes, Pseudomonas aeruginosa and Proteus vulgaris. Antifungal agent have been studied in Candida albicans and Candida vulgaris. These results indicate aqueous extract Acmella oleracea Effective reducing agents for green synthesis of ZnO NPs with significant antimicrobial potential. Key word: Acmella oleracea, Zinc Oxide nanoparticles, FTIR, XRD, FE-SEM, Antibacterial Activity, Antifungal Activity. ————————————————————
