An easily prepared hypersensitive water-soluble fluorescent probe for mercury(II) ions.
A hypersensitive water-soluble fluorescent probe, dansyl-L-tryptophan methyl ester (1), was easily prepared for the detection of Hg(2+) with a significantly improved detection limit (5 nM vs. 500 nM) in buffered aqueous solution.
