A label-free DNA biosensor with high sensitivity and selectivity is constructed by using DNA–Ag NCs and Exo III-catalyzed target recycling amplification.
An isothermal electrochemical method for the highly sensitive detection of mercury ions (Hg2+) was established based on Hg2+-triggered exonuclease III-aided target recycling amplification.
Isothermal amplification techniques for nucleic acid detection have drawn increasing interest recently due to the simplicity and low-cost of instruments.
