Ag(I)-coordinated hairpin DNA for homogenous electronic monitoring of hepatitis C virus accompanying isothermal cycling signal amplification strategy.This work designs a new homogenous electronic monitoring platform for sensitive detection of hepatitis C virus (HCV) on an immobilization-free Ag(I)-assisted hairpin DNA through the cytosine-Ag(+)-cytosine coordination chemistry.  The assay consists of target-induced Ag(+) dissociation from hairpin DNA and an isothermal circular strand-displacement polymerization (ICSDP) reaction.
