## Abstract A highly selective fluorescence sensor was developed for Hg(II) ion detection in aqueous solutions based on the selective binding of Hg(II) ions with a pair of thymine‐thymine mismatch. The sensor consists of two DNA probes functionalized with a fluorophore (fluorescein, F) and a quench
Contamination with heavy metal ions may have severe effects on human health and the environment. Mercury contamination is widespread and arises from a variety of natural sources, such as oceanic and volcanic emissions, [1] as well as anthropogenic sources, [2] such as gold mining and the combustion
