Metallic oxide nanoparticles showed cytotoxicity against cancerous cells via ROS generation. TiO2 and ZnO nanoparticles and their composites have been synthesized by chemical route. Their structural properties indicate the anatase phase of TiO2 while ZnO formed has shown hexagonal wurtzite structure. The SEM images showed that TiO2 NPs are formed in very small and uniform spherical morphology while ZnO formed in the form of small nanorods. The band gap and ROS generation of TiO2 reduces when it’s composite has been made with ZnO nanorods.
