Figure 6: ROS production of four types of TiO2 NRs: (a) bare (b) DA functionalized NRs (inset shows scale enlargement to show that there is a small activity that can be observed). Samples are background corrected; fluorescence of the sample kept in dark is subtracted from the fluorescence of the irradiated sample.
