Fig. 7. Fluorescence imaging (pseudocolor) of H₂O₂ in Kunming mice. (a) Only 12 (20 μM, 100 μL) was injected as a control. (b) Mouse pretreated with rotenone for 1 h and then injected with 12. (c) Mouse successively injected with rotenone, NAC, and 12. (d) Relative fluorescence intensities of (a–c). Adapted with permission from ref. 36c. Copyright 2013 American Chemical Society.
