摘要

A simple synthetic approach of water-soluble and stable fluorescent copper nanoclusters (Cu NCs) at room temperature was proposed. The cysteamine functionalized nanoconjugate materials (CA-Cu NCs) exhibited variety of exceptional properties, including good water-solubility, photostability, low cytotoxicity and acting as an excellent cell imaging probe. Based on the electron transfer and aggregation induced fluorescence quenching mechanism, CA-Cu NCs were utilized in the selective determination of ferric (Fe³⁺) and iodide (I⁻) ions. The detection limits of Fe³⁺ and I⁻ ions were calculated as 423 nM and 2.02 μM, which are lower than the maximum level of Fe³⁺ and I⁻ ions, allowed in drinking water by the U.S. Environmental Protection Agency. The assay method of paper strip was also successfully applied for the detection of Fe³⁺ and I⁻ ions in live cells and human urine.
