A New Fluorescent Chemodosimeter for Hg2+: Selectivity, Sensitivity, and Resistance to Cys and GSH
On the basis of the mechanism of Hg2+-promoted hydrolysis, a new fluorescent chemodosimeter (Rho-Hg1) is reported for single-selective and parts per billion level-sensitive detection of Hg2+ in natural waters. Moreover, the fluorescence response of Rho-Hg1 to Hg2+ has little interference from sulfur...

Summary: | On the basis of the mechanism of Hg2+-promoted hydrolysis, a new fluorescent chemodosimeter (Rho-Hg1) is reported for single-selective and parts per billion level-sensitive detection of Hg2+ in natural waters. Moreover, the fluorescence response of Rho-Hg1 to Hg2+ has little interference from sulfur compounds such as cysteine and glutathione and could be used in the Hg2+ imaging in living cells. |
