A novel electrochemical biosensor for selective determination of mercury ions based on DNA hybridization

An electrochemical biosensor was developed for Hg2+ determination based on DNA hybridization. In the presence of Hg2+, the target and probe DNAs with thymine–thymine (T–T) mismatches could hybridize by forming T–Hg2+–T complex. This induced DNA hybridization led to the decrease in reduction peak cur...
