| المستخلص : | Background: Bacteria are the smallest and most numerous organisms that can cause many serious human diseases. Objective: This work was carried out to study the antibacterial activity of CuO nanoparticles (CuO NPs) which have been prepared by laser ablation of a copper target immersed in deionized water using Q-switched pulsed Nd:YAG laser. Results: UV-Vis spectrophotometer exhibited two peaks of absorption spectra of CuO NPs colloidal one peak at uv-region (205 nm) and another peak at visible region (636 nm) and transmission electron microscopy (TEM) showed the morphology of prepared CuO NPs that were spherical and the particle size ranged from 10-100 nm. CuO NPs exhibited significant reduction on the viability of bacteria by reduction their optical density. Conclusion: Pulsed laser ablation in liquid was a successful method to produce metal NPs with suitable particle size and the antibacterial activity of CuO NPs against Escherichia coli ATCC 25922 and Staphylococcus aureus ATCC 25923 was effective especially at high concentrations. |
