This research concerns the preparation, characterization and antimicrobial activity of zinc oxide nanoparticles. In the present work, zinc oxide nanoparticles were synthesized from zinc acetate sources using sodium hydroxide as a precipitating agent by the co-precipitation method. ZnO nanoparticles were synthesized from the precursors of Zn (CH3COO)2.2H2O and NaOH by the co-precipitation method. In these processes the concentration of solutions was prepared as a three solution (0.1 M) by mixing ZnCl2 and Na2S solution. The prepared ZnO nanoparticles were covered with ZnS using a solution-based chemical method at a low temperature. The characterization processes (antimicrobial activity) were performed. In this research, ZnO-ZnS core shell nanoparticles were characterized by antimicrobial activity at the temperature 300˚C and 500˚C. The antimicrobial activity of prepared ZnO nanoparticles on six microorganisms (Bacillus subtilis, Candida albicans, Escherichia coli, Pseudomonas fluorescens, Staphylococcus aureus, and Salmonella typhi) was investigated by the Agar well diffusion method. It was found that high activity on Escherichia coli, medium activity on Bacillus subtilis, Candida albicans & Staphylococcus aureus and low activity on Pseudomonas fluorescens & Salmonellatyphi. | ||||||
