A label-free DNA biosensor with high sensitivity and selectivity is constructed by using DNA–Ag NCs and Exo III-catalyzed target recycling amplification.
A versatile exonuclease-assisted target recycling amplification strategy is demonstrated to achieve label-free chemiluminescence detection of DNA and construction of a series of two-input molecular logic gates.
A sensitive method for Ochratoxin A detection was developed which combines the advantages of label-free dsDNA-templated copper nanoparticles and exonuclease-catalyzed recycling amplification.
