Mercury is one of the deadly toxic metals to humans. A new fluorescent probe CS-Hg for Hg2+has been designed and synthesized based on the Hg2+-promoted cyclization and the CS NIR platform. The probe upon interaction with different metal ions showed good sensitivity and high selectivity for Hg2+through fluorescence “turn-on”response in PBS buffer. Significantly, the probe CS-Hg is highly reactive to Hg2+with a very rapid response. Furthermore, we have demonstrated that the probe is applicable for Hg2+imaging in the living cells and in animals. ©201...
