It can cause serious effects on the human health, such as case damage in the brain, nervous system, immune system, and kidney failure. Therefore, development of an accurate, sensitive, and simple operational detection method for mercury is very necessary. Herein, we report a new strategy for mercury ion detection based on commonly used PCR technique. High selectivity and sensitivity were achieved by the formation of the thymine\u2010Hg\u2010thymine (T\u2010Hg\u2010T) unnatural base pair at the 3\u2019\u2010end of PCR primers. The detection results of PCR amplification in presence of mercury ion could be reported either by using agarose gel analysis or through real\u2010time fluorometric dye tracing for different detection purposes. To our knowledge, this study represents the first application of PCR based technique to the detection of metal ions.<\/jats:p>","DOI":"10.1002\/elps.201900324","type":"journal-article","created":{"date-parts":[[2019,12,2]],"date-time":"2019-12-02T05:20:35Z","timestamp":1575264035000},"page":"1517-1522","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Ion\u2010induced PCR strategy for mercury detection"],"prefix":"10.1002","volume":"41","author":[{"given":"Gangyi","family":"Chen","sequence":"first","affiliation":[{"name":"Natural Products Research Center Chengdu Institution of Biology Chinese Academy of Science  Chengdu P.
