Abstract

Based on the principle of fluorescence recovery, by the strong and specific interaction between iodide (I−) ions and nanoAg on the surface of carbon nanodots/silver (Cdots/Ag) nanocomposites, we propose a simple label-free and turn-on method for the detection of I− ions with high selectivity and sensitivity by using fluorescent Cdots/Ag nanocomposites in aqueous media.
