Fig. 8. ROS generation upon white light irradiation and PDT study of TTNIR. (A) Relative change in fluorescence intensity (I/I0) at 534 nm of H2DCF-DA, TTNIR, and mixtures of TTNIR and H2DCF-DA in PBS upon white light irradiation for different times. Concentrations: 10 μM (TTNIR) and 5 μM (H2DCF-DA). (B) Cell viability of HeLa cells stained with different concentrations of TTNIR in the absence or presence of white light irradiation.
