A Self-Assembled G-Quadruplex/Hemin DNAzyme-Driven DNA Walker Strategy for Sensitive and Rapid Detection of Lead Ions Based on Rolling Circle Amplification

Herein, a sensitive biosensor is constructed based on a novel rolling circle amplification (RCA) for colorimetric quantification of lead ion (Pb(2+)). At the detection system, GR5 DNAzymes are modified on the surface of an immunomagnetic bead, and Pb(2+) is captured by the aptamer, inducing the disi...
