石墨烯量子点
Graphene Quantum DotsGraphene Quantum Dots (GQDs) are zero-dimensional carbon nanostructures with sizes typically below 20 nm, exhibiting quantum confinement and edge effects. They are widely used for fluorescence-based sensing due to their high photostability and tunable optical properties. / 石墨烯量子点（GQD）是尺寸通常小于20纳米的零维碳纳米结构，表现出量子限制和边缘效应。由于其高光稳定性和可调谐的光学性质，它们被广泛用于基于荧光的传感。
