This review focuses on the research progress related to carbon dots (CDs) derived from Chinese herbal medicines and tea, covering preparation methods, physicochemical properties, and application fields. It elaborates on preparation approaches like hydrothermal, solvothermal, microwave-assisted, and ultrasonic-assisted methods, and their influence on CDs' structure and properties. It also explores CDs' structural and optical properties. The application fields include antibacterial, sensing, bioimaging, photocatalysis, hemostasis, and energy. Carbon dots show antibacterial activity by destroying bacterial cell membranes, they can detect various substances in sensing, are important for bioimaging, degrade organic pollutants in photocatalysis, have hemostatic and anti-inflammatory effects, and can be used as battery anode materials. Despite progress, challenges remain in improving yield, quantum yield, property control, and understanding their mechanism of action. This review provides a reference for related research and looks ahead to future directions.
本综述聚焦于源自中草药和茶叶的碳点（CDs）的研究进展，涵盖制备方法、理化性质及应用领域。阐述了水热法、溶剂热法、微波辅助法和超声辅助法等制备方法及其对碳点结构和性质的影响。还探讨了碳点的结构和光学性质。应用领域包括抗菌、传感、生物成像、光催化、止血和能源等。碳点通过破坏细菌细胞膜展现抗菌活性，在传感中可检测各种物质，对生物成像很重要，在光催化中降解有机污染物，具有止血和抗炎作用，还可作为电池负极材料。尽管取得了进展，但在提高产率、量子产率、性能控制以及理解其作用机制方面仍存在挑战。本综述为相关研究提供参考并展望未来方向。
