Fund Project: This work was supported by the fund of China Tobacco Yunnan Industrial Co. (No. 2015JC05), the Foundation of the Department of Science and Technology of Yunnan Province of China (Nos. 2013HB062, 2014HB008), and Training Project (No. XT412003) of Yunnan University.

A rhodamine-based sensor has been developed for the detection of mercuric ions. The colorimetric and fluorescence responses, allowing naked-eye detections, are based on Hg²⁺-induced opening of the rhodamine spirocycle. Among all the testes ions, only Hg²⁺ generated a significant fluorescence enhancement of up to 30'-fold, with a bright yellow-green emission. This sensor was a low toxic compound, and was successfully applied in the in vivo imaging of Hg²⁺ in Spill 2 cells and C. elegans. This approach provides a sensitive and accurate method for the estimation of Hg²⁺ in environmental, tobacco and biological applications.
