Scholarcy highlights

  • A simple and facile strategy for the synthesis of fluorescent Cu NCs was developed
  • The obtained Cu NCs can be used for imaging ferric ions in living cells
  • The FL of the tannic acid-Cu NCs shows no changes with the addition of Fe2+ or H2O2 individually
  • The Cu NCs-based FL probe showed long-term stability, good biocompatibility and very low cytotoxicity. It was successfully used for imaging ferric ions in living cells, suggesting the potential application of Cu NCs fluorescent probe in clinical analysis and cell imaging
