Summary: Developing nanohybrid composition based fluorescent carbon dots (CDs) for ratiometric detection of copper ions is highly appealing. A ratiometric sensing platform (GCDs@RSPN) for copper ions detection has been developed by loaded green fluorescence carbon dots (GCDs) on the surface of red emission semiconducting polymer nanoparticles (RSPN) through electrostatic adsorption. The GCDs, featuring abundant amino groups, can selectively bind copper ions to induce the photoinduced electron transfer, leading to fluorescence quenching. A good linearity within the range of 0-100 mu M is obtained, and the limit of detection (LOD) is 0.577 mu M by using obtained GCDs@RSPN as ratiometric probe to detect copper ion. Moreover, the paper-based sensor derived from GCDs@RSPN was successfully applied for the visual detection of Cu2+.

Summary: Copper (Cu2+), a heavy metal, can accumulate in the human body and cause various diseases and health risks. In this study, a glutathione modified quantum dot (GSH-CdTe QDs) was synthesized and used as a turn-off fluorescence probe for the rapid detection of Cu2+. The fluorescence of GSH-CdTe QDs could be quickly quenched in the presence of Cu2+ through aggregation-caused quenching (ACQ), resulting from the interaction between the surface functional groups of GSH-CdTe QDs and Cu2+ and the electrostatic attraction. The proposed approach has been successfully applied for the detection of Cu2+ in real samples with satisfactory results, providing a promising strategy for rapid, simple, and sensitive detection of Cu2+ in practical applications.
