Abstract Nanotechnology is a recent field of modern research dealing with synthesis, strategy and manipulation particle’s structure in size range 1–100 nm. This study introduces one the methods synthesis nanoparticles, i.e., green ZnO NPs using aqueous leaf extract Becium grandiflorum (AM: ‘Yedegamentisie’). The biomolecules plant (such as phenols, flavonoids, saponins, glycosides, steroids, ta...
