Photoexcited TC-WS-CQDs improved killing cells. Huh7 cells were treated with or without TC-WS-CQDs and exposed to 470 nm irradiation for 10 min. After 24 h incubation, the cell morphology was observed by optical microscope (A). The cell proliferation was assessed by CCK8 assay (B) and MTS assay (C). Microscope image (the left panel) and statistical analysis (the right panel) showed cell migration capacity by wound healing assay (D). The data are mean ± SD (n = 3, statistical significance was analyzed via two-way ANOVA in B and C, statistical significance was analyzed via Mann–Whitney test in D, ****p < 0.0001, ns: not significant). CQDs + I470nm: TC-WS-CQDs with 470 nm irradiation, I470nm: 470 nm irradiation without TC-WS-CQDs, CQDs: TC-WS-CQDs, Control: no TC-WS-CQDs and irradiation
