Cu1-x FexO (x=0,0.05,0.10,0.15) nanoparticles with average particle size of 40 nm were prepared by sol–gel method. The obtained nanoparticles have been characterized by X-Ray Diffraction (XRD), Transmission Electron Microscopy (TEM) and UV–Vis Spectroscopy. Optical studies show that the Optical band gap of the samples decrease with doping. X-ray diffraction patterns of the samples confirm the presence of cupric oxide (CuO) phase. The effects of dopant level on the physical and antibacterial properties of the NPs have been investigated. The effect of dopant incorporation on antimicrobial activities of CuO:Fe nanoparticles on Escherichia coli (E. Coli) was investigated.
