In this paper, a novel electrochemical biosensor for Hg 2+ determination based on Hg 2+ -induced DNA hybridization is reported. A pair of oligonucleotides with seven strategically placed thymine-thymine (T-T) mismatched bases was introduced. Firstly, one oligonucleotide (P1) modified with hexanthiol
