a) Self-indication of cellular behaviors and time-dependent drug release of PaIr NPs (10 μM) by observing the dual-color fluorogenic process of Pa and Ir. The scale bar is 50 μm. b) Quantification of the dual-color fluorogenic process in a) by ImageJ. *p<0.05. ***p<0.001. c) Lysosomes colocalization of PaIr NPs in U87-MG cells. Cells were treated with the identical procedures of a), and stained with LysoTracker™ Green DND-26 for 30 min, then observed by CLSM. The scale bar is 50 μm. d) Quantification of the lysosomes colocalization. Pearson’s correlation coefficient was employed to denote colocalization efficiency.
