Label-free tungsten disulfide quantum dots as a fluorescent sensing platform for highly efficient detection of copper (II) ions

doi:10.1088/1674-1056/26/6/066102

Abstract

A fluorescent probe for the sensitive and selective determination of copper ion (Cu²⁺) is presented. It is based on the use of tungsten disulfide quantum dots (WS₂ QDs) which is independent of the pH of solution and emits strong blue fluorescence. Copper ions could cause aggregation of the WS₂ QDs and lead to fluorescence quenching of WS₂ QDs. The change of fluorescence intensity is proportional to the concentration of Cu²⁺, and the limit of detection is 0.4 μM. The fluorescent probe is highly selective for Cu²⁺ over some potentially interfering ions. These results indicate that WS₂ QDs, as a fluorescent sensing platform, can meet the selective requirements for biomedical and environmental application.
