Abstract

In the current study, nanoparticles (NPs) of zinc oxide (ZnO) were prepared followed by determination of their characters among chemical and biological tools. In aqueous media from zinc acetate dihydrate and sodium hydroxide ZnONPs were fabricated by a precipitation method. To characterize the physicochemical properties of ZnO NPs transmission electron microscopy (TEM) and X-ray diffraction (XRD) were applied. The chemically fabricated ZnONPs (cZnO NPs) characterized with by crystalline structure with hexagonal structure of the wurtzite. The morphology of cZnO NPs was spherical with a primary size of 5-30 nm. Aqueous leaves extract of Ocimum sanctum was used for biological preparation, which may be more ecofriendly and economical compared to other commonly used methods. Results of XRD patterns confirmed the crystalline nature of biologically fabricated ZnONPs (bZnO NPs). Electron micrographs revealed that the resultant bZnO NPs characterized by a spherical shape and a particle size ranged from 8.92 to 37.9nm.The results revealed the crystalline nature of biologically produced ZnO NPs (bZnO NPs). Electron micrographs of the fabricated ZnO NPs also were identified with spherical shape and a particle size distribution of 8.92-37.9 nm.
