A Simple and Sensitive Nanogold RRS/Abs Dimode Sensor for Trace As(3+) Based on Aptamer Controlled Nitrogen Doped Carbon Dot Catalytic Amplification
Using citric acid (CA) and ethylenediamine (EDA) as precursors, stable nitrogen-doped carbon dots (CD) nanosols were prepared by microwave procedure and characterized in detail. It was found that CD(N)s catalyze ethanol (Et)-HAuCl(4) to generate gold nanoparticles (AuNPs), which have strong surface...
