Abstract

Gold nanoparticles (Au NPs) decorated on zinc oxide nanorods (ZnO NRs) arrays by combining hydrothermal method toward ZnO nanorods template and subsequent decoration on Au NPs on the ZnO surfaces by DC magnetron sputtering. The hybrids Au NPs-ZnO NRs were characterized using field-emission scanning electron microscopy and energy-dispersive X-ray spectroscopy. The average diameter and length of ZnO NRs template were estimate at 80 and 430 nm, respectively. In addition, antibacterial tests confirmed that adding Au NPs enhances antibacterial effect.
