title: Au(III)-assisted core-shell iron oxide@poly(o-phenylenediamine) nanostructures for ultrasensitive electrochemical aptasensors based on DNase I-catalyzed target recycling.
abstract: A redox-active Au(III)-assisted core-shell iron oxide@poly(o-phenylenediamine) nanostructure was designed as a sensing platform for ultrasensitive electrochemical detection of small molecules (ATP, used as a model here) by coupling with DNase I-catalyzed target recycling.
