Target-induced conjunction of split aptamer as new chiral selector for oligopeptide on graphene-mesoporous silica-gold nanoparticle hybrids modified sensing platform

A new electrochemical label-free biosensor based on target-induced conjunction of a split aptamer as new chiral selector for oligopeptide using graphene-mesoporous silica-gold NP hybrids (GSGHs) as magnified sensing platform is firstly reported, which showed high sensitivity and selectivity for the detection of D-vasopressin (D-VP).
