title: A highly selective and sensitive fluorescent probe for Hg(2+) imaging in live cells based on a rhodamine-thioamide-alkyne scaffold.
abstract: A new fluorescence turn-on probe for Hg(2+) imaging in living cells was judiciously designed based on the interactions of Hg(2+) to both thiol and alkyne moieties in a rhodamine scaffold, and the likely novel sensing mechanism has been proposed.
