Abstract
We present the cooperative dehybridisation of DNA-gold nanoparticle conjugate (DNA-AuNP) assemblies induced by reduced salt concentration ([salt]), which can be precisely controlled by various conditions. The detection of Ag+ based upon the [salt]-induced dehybridisation of DNA-AuNP assemblies is five times more sensitive than that achieved under conventional thermal melting conditions.
