Electrochemical Analysis of CuO NPs in Artificial Saliva at Different Concentrations, pH, and Scan Rates Using Cyclic Voltammetry

In this study, the effect of nanoparticles of copper oxide (CuO NPs) dissolved in heat polymerizing acrylic-based soft liner was studied in artificial saliva that was used in the total denture in the mouth was identified, using the electrochemical method, to characterize the extent of the effect of nanoparticles on the oral cavity. Different concentrations (0.3% and 0.5% CuO NPs), pH, scan rates, and reproducibility were studied. The study concluded that the low percentage of 0.3% CuO NPs has less effect than the percentage of 0.5% CuO NPs by redox reaction in the artificial saliva. Furthermore, the acidic pH of the medium has less affected in oxidant that shows reduction peak appeared in the range of pH 2-6, so the nanoparticles of CuO save the acidity of the mouth, while the alkaline pH causes the oxidative effect in the artificial saliva. It can be used the nano copper to improve the chemical properties in the mouth medium.
