This manuscript aims to illustrate some of the current industrial and biological applications of copper oxide (Cu₂O) nanoparticles, where nanoparticles are of particular interest because of their multiple applications, as well as antibacterial and antiviral. In addition to the industrial applications such as ink permeability, sensing and carriers in solar cells, the obvious properties of finely processed Cu₂O is discussed along with different preparation methods through which Cu₂O nanoparticles are obtained. It is widely accepted that pulsed
laser ablation is one of the most successful Cu₂O fabrication techniques. , where this study focus on preparation and characterization copper nanoparticles doped Silver nanoparticles (Cu₂O@Ag) for optoelectronics, and bio-applications I can’t understand this sentence, please revise it.
