摘要: Abstract The antimicrobial power of a Cu/Zn mixed oxide was probed by viability study against E. coli . A facile, environment friendly synthesis CuO, ZnO and Cu 0.73 Zn 0.27 O nanoparticles carried out via hydroxycarbonate precursors the samples characterized several techniques. efficacy was, then, two independent growth inhibition essays, culture methods optical density after 4 h, 8 h 24 h contact time shows both concentration dependency. Remarkably exhibits highest activity, with 90% already for dose 200 μg/mL whereas CuO reaches same performance only has, comparatively, limited activity.
