A Novel Cu(2+) Quantitative Detection Nucleic Acid Biosensors Based on DNAzyme and “Blocker” Beacon
In this paper, a “turn-off” biosensor for detecting copper (II) ions based on Cu(2+)-dependent DNAzyme and a “blocker” beacon were developed. Upon the copper ion being added, the Cu(2+)-dependent DNAzyme substrate strand was irreversibly cleaved, thereby blocking the occurrence of the ligation react...
