| Abstract: |
| In recent years, heteroatom-doped carbon dots have attracted much attention due to their superior performances, among which nitrogen-doped carbon dots（N-CDs） have been most widely studied. N-CDs have higher quantum yields and luminescent properties compared to ordinary carbon dots. Due to their excellent water solubility, low toxicity, satisfactory biocompatibility, and good tissue permeability, N-CDs have shown great application prospects in biological analysis and detection, antibacterial agents, biomedical imaging, and disease treatment. Herein, the relevant properties and synthesis strategies of N-CDs and related applications in the biomedical field have been briefly reviewed. |
