Nanoparticles are widely used in the biotechnology and biomedicalfield. Green synthetic methods of nanoparticles are a simple and environmentallybenign process that declines the demerits of conventional chemical andphysical methods. The synthesis of semiconductor and metal nanoparticles is a risingdo research part, due to the possible applications in the progress of new technologies.The present research information the synthesis and characterization of zinc oxide nanoparticles (ZnO NPs) using C. Sinensis leaf extract. The findings of these studies show the green synthesized ZnO NPs are effective, safe, and eco-friendly as they arestable and have abundant flower shapes with maximum particles in size ranging from 100 nm indiameter. The synthesized ZnO NPs have been tested against the pathogenic microorganismsand showed an excellent zone of inhibition. DPPH radical scavenging activity of synthesized ZnO NPs expressed DPPH free radicals as a percentage of inhibition andIC50value of 70.37%. Acetylcholine esterase (AChE) inhibitory activity possesses the maximum amount of the synthesized ZnO NPs. Since the results ofthe current work, it was concluded that the synthesized ZnO NPs exhibited significant antibacterial and acetylcholine esterase inhibitory activities. Hence it can beused as a drug with multifunction in treating Alzheimer’s disease (AD).
