Abstract

Simultaneous detection of gasotransmitters such as NO and H2S is a crucial task to investigate the complicated relationship between NO and H2S. In this work, we presented a new approach to construct a dual response fluorescent probe for NO/H2S by step-wise functionalization of polysiloxanes. A near-infrared (NIR) and two-photon (TP) fluorescent probe, P-CYN, was fabricated for respectively visualizing H2S and NO in vivo. This work presented a powerful tool for the investigation of the relationship between gasotransmitters, and provided a valid strategy for further design of dual-response fluorescent probes.
