A Simple and Sensitive Nanogold RRS/Abs Dimode Sensor for Trace As<sup>3+</sup> 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<sub>N</sub>s catalyze ethanol (Et)-HAuCl<sub>4</sub> to generate gold nanopar...
