1.Light emitting device
Graphene quantum dots can be used for the construction of carbon-based light-emitting devices after being effectively controlled by doping, surface modification, etc. . Compared with traditional LED light-emitting devices, graphene quantum dots are made of light-emitting materials. Carbon-based light-emitting devices have better stability, while avoiding potential heavy metal pollution.
2.Optical probe
Graphene quantum dots can achieve highly sensitive detection of ions, biomolecules, free radicals, etc. by means of doping and surface group modification. The detection limit can reach 10-6M to 10-12M. Compared with the traditional detection technology, this solution has higher sensitivity and anti-interference ability.
3.Bioimaging
Graphene quantum dots have good biocompatibility, stability, anti-interference ability and fluorescence performance. Therefore, graphene quantum dots can be used as an ideal cell fluorescence imaging agent for cell and tissue imaging.
Graphene quantum dots have abundant surface groups, and can be used for tumor diagnosis and targeted therapy based on graphene quantum dots through surface targeting agent modification and drug loading. At the same time, with the excellent fluorescence performance of graphene quantum dots, while targeting therapy, it can realize real-time fluorescence monitoring of tumor tissues and achieve long-term visualization of the entire treatment process.
