This study uses economical and ecologically friendly techniques to create gold nanoparticles (Au-NPs) and copper nan]oparticles (Cu-NPs) utilizing distilled water (DW) solution and the liquid pulse laser ablation (PLAL) technique with a wavelength of 1064 nm and varying laser intensities. Using X-ray diffraction (XRD) and absorption spectrometry, the characteristics of Au-NPs and Cu NPs as well as Au-CuNPs were investigated. The results indicated that a crystal structure for gold (Fcc) had formed.The appearance of the surface plasmon resonance (SPR) peak at 523 nm in the UV visible spectrum in the Uv-Vis data demonstrated the creation of Au NPs. Cu NPs and Au NPs nanoparticles (Au-CuNPs) have antibacterial properties against E. coli and Staph aureus. This is because the high surface-to-volume ratio offers provides a more effective means of enhancing bacterial activity as measured by the area of inhibition. provides a more effective means of enhancing bacterial activity as measured by the area of inhibition. There are numerous opportunities to investigate nanoparticles' theranostic role in molecular imaging thanks to recent developments in nanotechnology and nanomaterials. In molecular imaging, gold nanoparticles have been widely used as contrast agents and drug delivery systems. This is because of the exceptional qualities of gold nanoparticles, such as their high chemical stability, facile bioconjugation with different molecules, and outstanding biocompatibility with human cells. Gold nanoparticles can be created using different processes including conventional chemical synthesis, radiation technologies, electrochemical, bio-synthesizing and pulsed laser ablation in liquid (PLAL)
