Fig. 3From: Composition tunability of semiconductor radiosensitizers for low-dose X-ray induced photodynamic therapyTBR-mediated radiosensitization of cancer cells. A Confocal image of the U87MG cells after incubating with TBR-Cy5.5 for 24 h. Blue and red colors represented Hoechst 33,342 and Cy5.5 fluorescence, respectively. B The viability of U87MG cells treated with 4 Gy of X-ray irradiation or without X-ray irradiation, after incubation with different concentrations of TBR. C Flow cytometric analysis of U87MG cells after various treatments. D Fluorescent images of U87MG cells stained by DCFH-DA after different treatments. Green fluorescence indicated the presence of ∙OH. E Fluorescent images of U87MG cells in BODIPY-C11 staining assay. F Fluorescent images of U87MG cells in JC-1 staining assay. G Comet assay of U87MG cells after treatment with PBS, PBS + X, TBR or TBR + X (X: X‐ray irradiation, 4 Gy). H Clonogenic cell survival assayBack to article page
