Fig. 8. Fluorescence microscopy images of HeLa cells incubated with rGO/SE precursor (a) without irradiation and (b) with irradiation for 10?min; HeLa cells incubated with rGO/AuNCs/SE precursor (c) before and (d) after irradiation for 10?min; HeLa cells incubated with rGO/AuNCs/SE precursor loaded with 5-FU (e) before and (f) after irradiation for 10?min; each series can be classified to cell nucleus dyed in blue by Hoechst 33342, red by PI and the merged images of both, respectively.
