Fig. 3. (a) Fluorescence imaging of SC NPs in HSC3 cells: left panel, DAPI channel; middle panel, fluorescence images; right panel, merged images; up panel, planform; down panel, side view. (b) CCK-8 assays of HSC3 cells incubated with SC NPs in different conditions. (c) Apoptotic rates of blank HSC3 cells. (d) Apoptotic rates of HSC3 cells treated with SC NPs only. (e) Apoptotic rates of HSC3 cells treated with SC NPs and laser irradiation.
