Scholarcy highlights

  • In this paper, a simple and effective method was designed to synthesize hydrophobic carbon dots
  • The method was employed to intracellular imaging Al3+ in living cells
  • It was interestingly found that morin and its fluorescent metal-ion complex can successfully coordinate on the surface of amphiphilic fluorescent carbon dots, the emission of A-CDs completely overlapped the absorption peak of MR-Al3+
  • The fluorescence signals of the system were linearly correlated with the concentration of Al3+ over a range of 8–20 μM, with a detection limit of 0.113 μM
  • The method was successfully applied to image the distribution of Al3+ in Human Umbilical Vein Endothelial Cells
