Label-free and sensitive microRNA detection based on a target recycling amplification-integrated superlong poly(thymine)-hosted copper nanoparticle strategy
A label-free DNA biosensor with high sensitivity and selectivity is constructed by using DNA–Ag NCs and Exo III-catalyzed target recycling amplification.
In this paper, we describe a novel label-free fluorescence method for microRNA-21 (miR-21) detection based on terbium (Tb3+) and duplex-specific nuclease (DSN) assisted target recycling.
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.
