Size-dependent antimicrobial properties of CuO nanoparticles against Gram-positive and -negative bacterial strains

Abstract

The antibacterial activity of CuO nanoparticles was found to be size-dependent. In addition, the highly stable minimum-sized monodispersed copper oxide nanoparticles synthesized during this study demonstrated a significant increase in antibacterial activities against both Gram-positive and -negative bacterial strains.
