A Cascade Signal Amplification Strategy for the Ultrasensitive Fluorescence Detection of Cu(2+) via λ-Exonuclease-Assisted Target Recycling with Mismatched Catalytic Hairpin Assembly

Herein, an ultrasensitive DNAzyme-based fluorescence biosensor for detecting Cu(2+) was designed using the cascade signal amplification strategy, coupling λ-exonuclease-assisted target recycling and mismatched catalytic hairpin assembly (MCHA). In the designed detection system, the target, Cu(2+), c...
