Rapid on-site/in-situ detection of heavy metal ions in environmental water using a structure-switching DNA optical biosensor

A structure-switching DNA optical biosensor for rapid on-site/in situ detection of heavy metal ions is reported. Mercury ions (Hg(2+)), highly toxic and ubiquitous pollutants, were selected as model target. In this system, fluorescence-labeled DNA containing T-T mismatch structure was introduced to...
