Green synthesis of zinc oxide nanoparticles (ZnO NPs) is becoming increasingly importance as eco-friendly. The objectives of this study were the production of zinc oxide nanoparticles using parsley extract. Methods: In the present study, ZnO NPs were synthesized from an extract of parsley at different temperatures (at room temperature and 90°C) and obtained the optimum time for preparation of ZnO NPs. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Dynamic light scattering (DLS), and Diffuse Reflection Spectroscopy (DRS). The antibacterial activities of the samples were determined against Escherichia coli (E. coli). Results: XRD results of ZnO NPs were correctly synthesized and crystalline structure was similar to the previously reported pattern. The nanoparticle morphology was observed for ZnO nanostructured based on the SEM images. DLS analysis showed samples in the nanometer scale. The DRS absorption spectra of nanoparticles showed the Ultraviolet (UV) protective properties. The antibacterial activities against E.coli were observed because of the presence of ZnO NPs. Conclusions: This result showed that the parsley extract is good candidate for the synthesis of ZnO nanoparticles with antibacterial activities against Escherichia coli. The result indicated that ZnO NPs can have a good potential for different applications.   UR - https://www.nanomedicine-rj.com/article_31900.html L1 - https://www.nanomedicine-rj.com/article_31900_393f76bc5fa7290fc1b98d34405ecb33.pdf ER -
