3. INTRODUCTION
Copper
willingness to experience is quite
abundant and its size is quite cheap.
good conductor of heat and electricity
after silver. It has a lower toxicity for
human, when it is in nano size
Nanoparticles are very small materials that are less than 100 nm in size

4. • Cu Nanoparticle has a potential for various
applications and can be used widely in biomedical
fields such as drug prescribing
• antibacterial coating in medical devices
• synthetic bone
• antibacterial paint
• water and cloth cleaner and antibacterial bandage.

16. Conclusions
Synthesis of copper oxide nanoparticle (CuO NPs)
colloid with laser ablation method was successfully
carried out. Variation of distilled water solution, PVP
0.5 mM, 5 mM, and 10 mM obtained the most stable
colloid at a concentration of 5 mM. Based on the
results of the ultraviolet visible (UV-Vis) test in the
292 nm -306 nm spectrum, it shows the presence of
CuNPs, but it has a different peak of adsorbance. The
results of XRD analysis show the presence of
diffraction peaks shows that CuO nanoparticles
produced in this study contain CuO compounds.
