Graphene quantum dots (GQDs) are carbon-based, zero-dimensional nanomaterials and unique due to their astonishing optical, electronic, chemical, and biological properties. Chemical, photochemical, and biochemical properties of GQDs are intensely being explored for bioimaging, biosensing, and drug delivery. The synthesis of GQDs by top-down and bottom-up approaches, their chemical functionalization, bandgap engineering, and biomedical applications are reviewed here. Current challenges and future perspectives of GQDs are also presented.

石墨烯量子点（GQDs）是碳基零维纳米材料，因其具有令人惊叹的光学、电子、化学和生物学特性而独具特色。人们正在深入探索石墨烯量子点的化学、光化学和生物化学特性，以用于生物成像、生物传感和药物递送。本文综述了通过自上而下和自下而上方法合成石墨烯量子点、其化学功能化、带隙工程以及生物医学应用。还介绍了石墨烯量子点当前面临的挑战和未来前景。
