Fig. 3. Selectivity and specificity of the τ-probe to H2Sn. (a) Fluorescence lifetime changes caused by various reactive sulfur species, with or without Na2S4 (as a H2Sn donor). (b) Fluorescence lifetime changes caused by various reactive oxygen species, with or without Na2S (as a H2S donor). See experimental details in the Experimental section. All experiments were repeated at least three times. Error bars represent standard deviation.
