a) Mitochondrial localization of free dye and nanodroplet formulations. BPD and ICG signals were pseudo-colored in red. MitoTracker (Green) was used to stain mitochondria. Scale bar = 20 µm. b) Lysosomal localization of free dye and nanodroplet formulations. LysoTracker (Green) was used to stain lysosomes. BPD and ICG signals were pseudo-colored in red. Nuclear staining was done with Hoechst (blue) on both the panels. Scale bar = 20 µm.
