Abstract
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.
期刊介绍：
Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons.
Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
