Abstract

Abstract:-

This work consists of synthesis and characterization of Zinc oxide/ Cadmium Sulphide Nano-composites (ZnO/CdS NCs). ZnO nanoparticles (ZnO NPs) is prepared by using perspiration method then CdS is grown on the surface of ZnO NPs after modification. ZnO/CdS NCs are characterized by X-ray diffraction (XRD), Atomic Force Microscopy(AFM), and Field Emission Scanning Electron Microscopy (FE-SEM). Biological inhibition of prepared nanocomposites against Escherichia coli (E. coli ) Staphylococcus aureus (P. aureus) and Candida albicans( C. Albicans) are measured by disc diffusion assay method and compared with standard antibiotics ampicillin and clotrimazole. The proposed mechanism of anti-biological inhibition in presence of ZnO/CdS NCs in an aqueous solution was suggested.
