文摘

•: Copper nanoclusters (CuNCs) were synthesized by an interfacial etching approach.
•: CuNCs exhibited the size-dependent tunable photoluminescence.
•: CuNCs could be used as color indicator for pH detection.
•: CuNCs with good biocompatibility and low cytotoxicity are promising in bioimaging.
•: The CuNCs/DNA complexes have potential applications in efficient gene expression.
