Evaluation of physicochemical characteristics and antimicrobial activities of copper oxide nanoparticles formed by the solution combustion method

In this paper, copper oxide (CuO) nanoparticles (NPs) was prepared by solution combustion technique. We used copper nitrate as an oxidizer and malic acid as a fuel to make three different CuO NPs by using different fuel ratios: low (M1), stoichiometric (M2), and high (M3). The XRD patterns show that...
