Schematic representation regarding the four prominent ways of antimicrobial potential of CdS-CoxNi1-xFe2O4/SiO2/TiO2 nanocomposites, where (1) CdS-CoxNi1-xFe2O4/SiO2/TiO2 nanocomposites adhere to and wrapped the microbial cell surface and results in CdS NPs release which causing membrane damage and altered transport activity, (2) CdS-CoxNi1-xFe2O4/SiO2/TiO2 nanocomposites block the ions transport from and to the microbial cell, (3) CdS-CoxNi1-xFe2O4/SiO2/TiO2 nanocomposites increase the ROS (due to the activation after gamma irradiation) leading to cell damage, and (4) CdS-CoxNi1-xFe2O4/SiO2/TiO2 nanocomposites penetrate inside the microbial cells and interact with cellular organelles and biomolecules, and thereby affect respective cellular machinery. CdS NPs may serve as a vehicle to effectively-deliver Cd2+, and S2+ ions to the microbial cytoplasm and membrane, where proton motive force would decrease the pH to be less than 3.0 and therefore improve the release of Cd2+, and S2+ ions.
