Two-dimensional quantum dots (2D-QDs) derived from two-dimensional sheets have received increasing interest owing to their unique properties, such as large specific surface areas, abundant active sites, good aqueous dispersibility, excellent electrical property, easy functionalization, and so on. A variety of 2D-QDs have been developed based on different materials including graphene, black phosphorus, nitrides, transition metal dichalcogenides, transition metal oxides, and MXenes. These 2D-QDs share some common features due to the quantum confinement effects and they also possess unique properties owing to their structural differences. In this review, we discuss the categories, properties, and synthetic routes of these 2D-QDs and emphasize their applications in electrochemical biosensors. We deeply hope that this review not only stimulates more interest in 2D-QDs, but also promotes further development and applications of 2D-QDs in various research fields.
源自二维薄片的二维量子点（2D-QDs）因其独特的性质，如大比表面积、丰富的活性位点、良好的水分散性、优异的电学性能、易于功能化等，而受到越来越多的关注。基于包括石墨烯、黑磷、氮化物、过渡金属二硫属化物、过渡金属氧化物和MXenes在内的不同材料，已经开发出了多种二维量子点。由于量子限域效应，这些二维量子点具有一些共同特征，同时由于其结构差异，它们也具有独特的性质。在这篇综述中，我们讨论了这些二维量子点的类别、性质和合成路线，并强调了它们在电化学生物传感器中的应用。我们深切希望这篇综述不仅能激发人们对二维量子点的更多兴趣，还能促进二维量子点在各个研究领域的进一步发展和应用。
