(a) Chemical structures of the molecular probes 24–26. CLSM images of living HeLa cells: (b) bright-field image of live HeLa cells after incubation with 24 (5.0 μM), 25 (10 μM), and 26 (5.0 μM) for 20 min, then with Angeli’s salt (200 μM) for 45 min; (c) CLSM image of (b), λ_ex = 405 nm, emission channel of 470–570 nm; (d) CLSM image of (b), λ_ex = 559 nm, emission channel of 600–680 nm; (e) CLSM image of (b), λ_ex = 635 nm, emission channel of 690–780 nm. The scale bar is 10 μm. (f) The chemical structure of the probe 26 and its chemodosimetric reaction. Figure 17(b–e) was reprinted from ref (45). Copyright 2016 Royal Society of Chemistry.
