Graphene Quantum Dots (GQDs)
Solvent: DI Water, Concentration: 0.1 mg/ml
Graphene Quantum Dots (GQDs) are a specialized subset of zero-dimensional nanocrystals derived from graphene semiconductors, notable for their distinct 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 advanced materials. High-quality GQDs are available from Nano Chicago.

Applications of Graphene Quantum Dots
Graphene Quantum Dots (GQDs) are widely used due to their excellent optical, electrical, and chemical properties. Key application areas include:
-
Optoelectronics: GQDs are employed 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 used for smart sensors to monitor plant health, detect environmental stress, and enable controlled release of fertilizers and pesticides.
-
Energy Storage and Conversion: GQDs enhance lithium-ion battery and supercapacitor performance by improving conductivity and charge storage. They are also studied for fuel cells and photocatalysis applications.
-
Environmental Applications: GQDs are applied in water purification, pollutant detection, and photocatalytic degradation of organic contaminants due to their high stability and redox activity.
