Aqueous Synthesis of Color-Tunable CuInS<sub>2</sub>/ZnS Nanocrystals for the Detection of Human Interleukin 6
In this Article, we present a facile
microwave-assisted synthesis route for the preparation of water-soluble
and high-quality CuInS<sub>2</sub>/ZnS nanocrystals (NCs) with glutathione
as the stabilizer. The as-prepared CuInS<sub>2</sub>/ZnS NCs exhibited
small particle sizes (∼3.3 nm), long photoluminescence lifetimes,
and color-tunable properties ranging from the visible to the near-infrared
by varying the initial ratio of Cu/In in the precursors. The low-toxicity,
highly luminescent and biocompatible CuInS<sub>2</sub>/ZnS NCs were
applied to cell imaging, showing that they could be used as promising
fluorescent probes. Furthermore, the CuInS<sub>2</sub>/ZnS NCs were
used as the signal labels for a fluoroimmunoassay of the biomarker
IL-6, showing their great potential for use as reliable point-of-care
diagnostics for biomarkers of cancer and other diseases
