Fig. 8. Real-time monitoring of fluorescence and morphology of HeLa cells treated with nanoprobe (10 μL) for 3 h and then NIR irradiation at a power density of 4 W cm–2 for different times (a–i) at an λ ex/em of 633/680–740 nm (top) and bright field (bottom). Scale bar, 25 μm. (j) Time course of fluorescence intensity obtained from the Leica software for a–i.
