Synthesis and antibacterial properties of copper nanoparticles for Salmonella typhi

In this study, the antibacterial properties of Cu nanoparitcles (Cu-NPs) were investigated against Salmonella typhi. The Cu-NPs were prepared by the reduction of cupper acetate with the help of ethylene glycol (EG), then sample was characterized by XRD for its average particle size identification. The antibacterial activity assessed by well diffusion and disc diffusion method on different concentration of nanoparticles. It was found that these Cu-NPs showed antibacterial activity in form of zone inhibition, wherein, zone of inhibition increased with increase in concentration of Cu-NPs.
