ExoIII and TdT dependent isothermal amplification (ETDA) colorimetric biosensor for ultra-sensitive detection of Hg2

•A colorimetric biosensor was constructed for ultra-sensitive detection of Hg2+•The activity of ExoIIIwas activated by T-Hg2+-T mismatch•The background value was reduced by inhibiting of TdT activity with -NH2•The TdT was activited for the formation of G-rich nucleic acid sequences•The cyclic amplif...
