title: A simple "molecular beacon"-based fluorescent sensing strategy for sensitive and selective detection of mercury (II).
abstract: A novel fluorescent sensor for the detection of Hg(2+) in aqueous media was developed. The method takes advantages of the highly selective thymine-Hg(2+)-thymine coordination and the sensitive "signal-on" structure-switching molecular beacon.
