Near-visible light induced ROS and evidence of the oxidative stress (a) near-visible light irradiation of TiO2 or Fe doped TiO2 NPs in the cell, (b) ROS causing NATA degradation in the cell, (c) High throughput screening (HTS) used to determine cell death accompanied by various oxidative stress pathways, (d) oxidative stress scavenger (NAC) for demonstrating the reduction of the phototoxicity. 45
