Hydrogen sulfide (H2S) is closely related to physiological diseases, environmental pollution, food safety, and plant growth. Herein, a new nopinone-based near-infrared fluorescent probe has been developed detect H2S with superior performance, including large Stokes shift, low detection limit, good selectivity, fast response time. NPD-H2S was used in water wine samples quantitatively. In addition, could be fabricate nanofiber membranes as portable tool for sensitively detecting vapor using smartphone. Moreover, effectively image HeLa cells, MCF-7 zebrafish. More importantly, the monitored presence of upregulation processes Arabidopsis thaliana under salt stress by bioimaging. This work provides concept intervention external stresses cultivation. Therefore, can monitor fluctuation environment living systems.
