Figure 2

Fluorescent spectra of 10 μM CD-MONT-2′ in DMSO treated with different substances.

(a) Addition of H2S after 15 min and the insert pictures were taken under Xe lamp before and finally treated with H2S after 15 min. (b) Continual addition of Na2S and the insert pictures were taken under Xe lamp. (c) Fluorescent intensity of (I-I0)/I0 (409 nm) spectra with 10 μM Na2S, 10 mM glucose and amino acids. (d) Fluorescent intensity of (I-I0)/I0 (409 nm) spectra with 10 μM Na2S, inorganic salts, RNS, ROS and RSS.
