摘要

Pulsed laser ablation in liquid (PLAL) represents one of the best physical techniques for producing high-purity nanoparticles from top to bottom. This study employed this method to synthesize CdO@ZnO core–shell nanoparticles using an Nd:YAG laser with a wavelength of 1064 nm at energies of 320, 520, and 720 mJ, respectively, with a total of 1000 pulses. The properties of the synthesized nanoparticles sample by UV-Vis spectroscopy, X-ray diffraction (XRD), and transmission electron microscopy (TEM) which showed that the nanocomposite has a spherical or sub-spherical shape with a size ranging 50 nm. The antibacterial activity was tested against gram-positive bacteria S. aureus and Gram-negative bacteria E. coli. The results showed that the CdO@ZnO core–shell nanoparticles made using the PLAL method are very good at killing bacteria and can fight bacteria that cause disease.
