A novel study of antibacterial activity of copper iodide nanoparticle mediated by DNA and membrane damage

► Copper Iodide was synthesized by modified co-precipitation method and chemically characterized. ► Antibacterial activity was studied by MIC, MBC, agar well diffusion assay and growth curve. ► ROS generation was detected and DNA damaging was observed. ► Cell membrane damage was found by AFM study.
