Fig. 5. Confocal microscope images of Ir-TEMPO1 and Ir-TEMPO2 in PC3 prostate adenocarcinoma cells. (a) Co-localisation with MitoTracker Green FM (400 nM; 30 min at 37 °C; λ_ex = 490 nm/λ_em = 516 nm). (b) Co-localisation with LysoTracker Green DND-26 (50 nM; 30 min at 37 °C; λ_ex = 504 nm/λ_em = 511 nm).
