Synthesis and biological application progress of nitrogen doped fluorescent carbon dots
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.
