Commercially available ZnO NPs were modified in aqueous solution of silver nitrate in the presence of the artificial radiation by using different sources of radiation such as high-power UV/Vis LED units and radioactive isotope 60Co. New nanocomposites were characterized by XRD, TEM, HRTEM, HRSTEM with 3D element mapping, DRS and PL spectrometry. The results showed that all samples were composed of Ag@AgCl NPs connected with ZnO NPs via stable heterojunction. The use of different radiation had significant influence on the prepared composites and the final antimicrobial activity against Gram-negative Escherichia coli, Pseudomonas aeruginosa, and Gram-positive Streptococcus salivarius, Staphylococcus aureus bacteria strains and yeast Candida albicans. The possible influence of irradiation on the final physiochemical and antimicrobial activity of Ag@AgCl/ZnO nanocomposites was proposed. It was found that the Ag@AgCl/ZnO irradiated by γ- and β-radiation exhibited the highest antimicrobial activity.
