Fig. 4. Colocalization images of the 4T1 cells stained with MitoTracker and CyOH–AgNP/CD (A–D). Green channel: λex = 488 nm and λem = 500–570 nm; red channel: λex = 633 nm and λem = 640–750 nm. Live/dead images of the 4T1 cells with calcein-AM and propidium iodide co-staining in the presence of PBS (E), AgNP/CD (F), CyOH (G), and CyOH–AgNP/CD (H).
