The pulsed laser ablation of a metallic target in the liquid (PLAL) is a modern and good method for creating a variety of nanomaterials that have piqued the interest of researchers in the last decade. It is used in this work to prepare zinc na-noparticles and zinc oxide nanoparticles (ZnPNs and ZnO NPs) using Nd: YAG laser with the two wavelengths (532 nm) and (355 nm) using the energies (600 mJ) and (500 mJ) respectively, and the number of the pulse (500, 600, 700, 800, and 900 Pulses); for each wavelength used in this work. The properties of the prepared NPs were studied by diag-nosing them by (UV-Vis, FTIR, AFM, XRD, SEM, and EDX) techniques. Then the antibacterial activity of the pre-pared nanoparticles was tested against two types of Gram-positive bacteria (Streptococcus mutans & Staphylococcus aureus) and two types of Gram-negative bacteria (Pseudomonas aeruginosa & Escherichia coli) isolated from the oral cavity. The finding showed that ZnNPs made using the PLAL approach could be employed to kill pathogenic and haz-ardous bacteria due to having antibacterial activity.
