Fig. 7. Epifluorescence study of sensors 9b and 10b (300 μM). Two photon image of sensor 9b (λ ex = 850 nm, λ em = 400–550 nm, max z-projection 80–100 μm); (b) as for (a) but sensor 10b. (c) comparison of co-localisation coefficients for sensors 9b and 10b with (i) Mitotracker and (ii) Lysotracker; (d) response over time of sensor 9b to exogenous (d) ZnCl2 and (e) 100 μM ZnCl2 co-administered with 5 μM pyrithione.
