Chem Commun (Camb). 2009 Aug 7:(29):4453-5. doi: 10.1039/b907386h. Epub 2009 Jun 12.

Abstract

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.
