(a) Decay profiles of the absorbance of DPBF centered at 410 nm in the presence of CSS-RB nanoconjugates, CSS nanoparticles and free Rose Bengal in ethanol/water solution irradiated with increasing X-ray doses. (b) Cell viability of U87 MG cells incubated with RB, CSS and RGD-CSS-RB with or without X-ray irradiation (4 Gy). (c) Cell viability of U-87 MG cells treated with varying amounts of RGD-CSS-RB in the presence or absence of X-ray irradiation (4 Gy). (d) Fluorescence images to show the uptake of RGD-CSS-RB (40 and 200 μg/ml) and X-ray induced intracellular 1O2 generation after incubation with U-87 MG cells for 24 hours. Scale bar represents 200 μm.
