Graphene Quantum Dots (GQDs)
Solvent: DI Water, Concentration: 1.0 mg/ml
Graphene Quantum Dots (GQDs) are a specialized subset of zero-dimensional nanocrystals derived from graphene semiconductors, distinguished by their honeycomb-patterned lattice structure. These nanocrystals are compact, with sizes ranging from 1–50 nm, providing exceptional versatility for applications across electronics, biomedicine, and material science. Their small size imparts remarkable electronic and optical properties, making GQDs ideal for innovative uses in energy, healthcare, and material engineering. High-quality GQDs are available from Nano Chicago.

Applications of Graphene Quantum Dots
Graphene Quantum Dots (GQDs) are widely applied due to their excellent optical, electrical, and chemical properties. Major application areas include:
-
Optoelectronics: GQDs are used in LEDs, photodetectors, and solar cells due to their strong and tunable photoluminescence.
-
Biomedical Applications: With high biocompatibility and low toxicity, GQDs are applied in bioimaging, biosensors, drug delivery systems, and photodynamic therapy for cancer treatment.
-
Sensors (Including Agricultural Sensors): GQDs enable highly sensitive detection of ions, molecules, and biomolecules. In agriculture, they are explored for smart sensors to monitor plant health, detect environmental stress, and enable controlled release of fertilizers and pesticides.
-
Energy Storage and Conversion: GQDs improve the performance of lithium-ion batteries and supercapacitors by enhancing conductivity and charge storage. They are also studied for fuel cells and photocatalysis applications.
-
Environmental Applications: GQDs are used in water purification, pollutant detection, and photocatalytic degradation of organic contaminants due to their high stability and redox activity.
