A new squaraine and Hg2+-based chemosensor with tunable measuring range for thiol-containing amino acids

A new squaraine, that undergoes absorption and fluorescence bleaching upon binding Hg2+, can serve as a turn-on colorimetric or fluorescent chemosensor for thiol-containing amino acids, presenting tunable measuring range by changing the concentration of Hg2+.
