Abstract
A novel method was used to transform pure metals to antimicrobial solutions by production of ZnO, Cu2O, MgO and TiO2 nanoparticles using rapid breakdown anodization (RBA) technique. The oxides’ nanoparticles were converted to their acetates by chemical reaction with acetic acid. After synthesize the acetates’ crystals they were dissolved in water to yield aqueous solutions. To evaluate the antibacterial activity of these solutions against pathogenic bacteria their inhibition zones were measured. X ray diffraction (XRD) technique and scanning electron microscope (SEM) were utilized to characterize these oxides. Before transforming to their acetates all mixed synthesized nanoparticles with deionized water did not have antibacterial activities but after transforming process Copper and Zinc acetates’ solutions had inhibition zones. Against S. aureus , S. epidermidis, Escherichia coli, Klebsiella pneumoniae and Candida albicans the inhibition zones for Copper acetate solution were 21, 19, 22, 22 and 30 mm respectively. For ZnO acetate solution these zones were 26, 25, 0, 0 and 14 mm respectively. There were no antibacterial activities recorded for both Titanium and Magnesium acetates’ solutions.
