Imaging of intracellular ATP in living cells treated by Ca2+ (5 mM) or etoposide (0.1 mM). CLSM images of the resultant TC/Apt in HeLa cells (a) and MCF-7 cells (c) treated by the Ca2+ or etoposide for another 30 min. Scale bars, 10 μm. Corresponding histograms of the mean fluorescence intensity of the TC/Apt in HeLa cells (b) and MCF-7 cells (d). * represents p < 0.05
