•CdO–ZnO nanocomposite was prepared by microwave-assisted method.•Nanocomposite was characterized with UV–Vis, FTIR, SEM, XRD and EDS.•CdO–ZnO nanocomposite has excellent antibiotics for biomedical applications.
CdO–ZnO nanocomposite was prepared by microwave-assisted method and characterized by X-ray crystallography (XRD), Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FT-IR). It exhibits hexagonal cubic structure with an average crystallite size of 27 nm. From the UV–Vis spectra, the bandgap is estimated as 2.92 eV. The fluorescence spectrum shows a near band edge emission at 422 nm. In addition the antibacterial activity of CdO–ZnO nanocomposite was carried out in-vitro against two kinds of bacteria: gram negative bacteria (G −ve) i.e. Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and gram positive bacteria (G +ve): Staphylococcus aureus, Proteus vulgaris and Bacillus spp. This study indicates the zone of inhibition of 40 mm has high antibacterial activity towards the gram positive bacterium S. aureus.
