According to the development of human life, control of the harmful effects of microorganismsis unavoidable. In the last decade, the development of nanotechnology has created opportunitiesto discover the antimicrobial effects of nanoparticles. In recent years, too much use of antibioticscauses many problems including poisonous effects and creating resistant types. Therefore,nanoparticle metal oxides have attracted deal attention. In this present work, the preparation ofZn۱-xCuxO hybrid nanocomposites Ag-doped has been reported. Polyethylene glycol was used asa stabilizer of nanoparticles to control the morphology and size of nanomaterials. FTIR, EDX,XRD, and SEM techniques investigate their structural, superficial, and morphological properties.The antibacterial behaviour of prepared nanoparticles was investigated against Gram-negative,Gram-positive Bacteria, and fungus showed excellent antibacterial activity. However, they weregenerally more sensitive to hybrid nanomaterials towards ZnO and CuO nanoparticles.
