A Novel Sensor for Sensitive and Selective Detection of Iodide Using Turn-on Fluorescence Graphene Quantum Dots/Ag Nanocomposite.


PMID 26256602

Abstract

Based on the principle of fluorescence enhancing, by the strong and specific interreaction between iodide (I(-)) ions and nanoAg on the surface of graphene quantum dots/Ag (GQDs/Ag) nanocomposite, we propose a simple label-free and turn-on method for the detection of I(-) ions with high selectivity and sensitivity by using fluorescent GQDs/Ag nanocomposite in aqueous media.
