“…This is due to its simplicity, effectiveness, ease of experimental setup, high purity (free of surface contamination), and the low number of chemical species required for production [10]. This technique uses high-intensity short pulses up to a nanosecond from an infrared laser source in the focusing condition to produce a tiny particle with unique properties in the nanoscale form via laser-matter interaction [11,12].…”

 Synthesis of ZnO nanoparticles was performed using PLAL with different wavelengths  The study and characterization of the ZnO nanoparticle were achieved.  The antibacterial activity of ZnO was studied on coli and S. aurous.  The nanomaterials were proved to have good biocompatibility and antibacterial properties.In recent years, biologists, chemists, materials scientists, and engineers have become interested in Nano-sized particles because of their unique properties. In this paper, ZnO nanoparticles were synthesized using an Nd: YAG laser with 800 mJ at 1064 nm and 532 nm (the fundamental and second harmonic wavelengths). The characteristics of optical, morphological, structural, wettability and antibacterial activity have been studied. The used technique of PLAL was successful in nanoparticle formation. It was proved in color changes, which was an indication of ZnO nanoparticle formation. The optical measurements show a decrease in absorption wavelength and an increase in the band gap, an indication of the formation of quantum confinement due to nanoparticle formation. The XRD involves the formation of polycrystalline ZnO at both wavelengths. Also, the FE-SEM proved the formation of nanoparticles with a semispherical shape and little agglomeration on the surface. However, the EDX shows Zn and O in the film, which means the formation of ZnO. The low contact angle indicates high wettability, which means that the material has high biocompatibility. Finally, the antibacterial test was done on two types of bacteria (E. coli and S. aurous) and showed an antibacterial effect on both types with different NP concentrations.
