| Abstract: |
| Graphene quantum dots (GQDs) are a kind of zero dimensional carbon nanomaterials, which have the advantages of small size, non-toxicity, good biocompatibility, good photostability, adjustable fluorescence, and good water solubility. GQDs can be endowed with different functions such as biological imaging, sound sensitivity, photothermal propertiesvia doping different heteroatoms and have a broad application prospect in the biomedical field. Several preparation methods of GQDs and their applications in biomedicine are reviewed. |
