(a) In vitro relative viabilities of Hela-luc cells incubated with UCNP–PEG–FA/PC70 (upconversion–nanoparticles–trismethylpyridylporphyrin–fullerene nanocomposite) at different concentrations, with (red) and without (black) 980 nm NIR light irradiation. (b) Relative viabilities of Hela-luc cells under nitrogen-purging conditions incubated with UCNP–PEG–FA/PC70 at different concentrations, with (red) and without (black) 980 nm NIR light irradiation. (c) Confocal images before (left) and after (right) NIR light irradiation. First line was stained with DiI and Hoechst 33 258, second line was stained with MitoRed and Hoechst 33258, third line was stained with PI and Lyso. Each group with three columns represent fluorescence image, optical image and merged image, respectively, from left to right.
