Highly sensitive and selective fluorescent chemosensors for Hg(II) in an aqueous environment based on carbamodithioate

Two highly sensitive (detection limits similar to 20 nM) and selective (selectivity > 30) fluorescent chemosensors were developed for detecting Hg2+ in a fully aqueous environment by using the rarely-studied carbamodithioate to create an Hg2+ binding site. (c) 2006 Elsevier Ltd. All rights reserved.
