Highly Sensitive and Selective Copper (II)-Catalyzed Dual-DNAzyme Colorimetric Biosensor Based on Exonuclease III-Mediated Cyclical Assembly
“Cu-DNAzyme” and “G4-DNAzyme” were used to develop a “turn-off” dual-DNAzyme colorimetric biosensor, which could be used to detect Cu<sup>2+</sup> by employing exonuclease III-mediated cyclical assembly (EMCA). EMCA was based on the cleavage activity of Cu<sup>2+</sup> to tra...
