The Inhibitory Action of Copper Oxide Nanoparticles (CuO NPs) against Escherichia coli as an Antibiotic

Abstract

This work shows the ability of copper oxide nanoparticles (CuO NPs) to prevent the growth of bacteria (Escherichia coli), and know the amount of concentration in which the effectiveness of these molecules lies against this type of bacteria, and this was done by examining CuO NPs and their spread in dishes petri containing bacteria colonies, with different concentrations
(100%, 75%, 50%, 25%, and 10%). The minimum total of these concentrations has been determined, at which the effectiveness of copper nanoparticle oxide molecules is shown to prevent growth, which has a value of 50 %, And then the effectiveness increases as the concentration increases until the concentration reaches 100%, and this complete focus is the ideal focus at Show it with cefotaxime antibiotic, so that it has the same amount of effect in the inhibition
