| Abstract: |
| As a class of fluorescent carbon-based nanomaterial with dimensions less than 10 nm， carbon quantum dots （CQDs）， with their quantum size effect， tunable surface functionality， and excellent biocompatibility， have demonstrated a potential for applications in the fields of chemical sensing， bioimaging， and photocatalysis. CQDs can be prepared from various carbon sources using different methods. Among them， biomass-derived CQDs （B-CDs） have become the focus of research in the field of nanomaterial due to their green synthesis pathway， renewable raw material advantage， and unique luminescent properties. This review summarized the synthesis strategy， carbon core-surface state synergistic regulation mechanism， functionalization modification technologies （doping/surface modification）， and its innovation for multi-disciplinary applications， aiming to provide theoretical references for the precise design and industrial application of B-CDs. |
