A Colorimetric Aptamer Sensor Based on the Enhanced Peroxidase Activity of Functionalized Graphene/Fe<sub>3</sub>O<sub>4</sub>-AuNPs for Detection of Lead (II) Ions

A Colorimetric Aptamer Sensor Based on the Enhanced Peroxidase Activity of Functionalized Graphene/Fe<sub>3</sub>O<sub>4</sub>-AuNPs for Detection of Lead (II) Ions

Lead (II) is regarded as one of the most hazardous heavy metals, and lead contamination has a serious impact on food chains, human health, and the environment. Herein, a colorimetric aptasensor based on the graphene/Fe<sub>3</sub>O<sub>4</sub>-AuNPs composites with enhanced p...
