Graphene Quantum Dots (GQD)

Nanografi presents high-quality Graphene Quantum Dots (GQDs) tailored to suit specific requirements.

What is the Graphene Quantum Dots?

Graphene Quantum Dots are nanoparticles with size less than 100 nm and mostly between 2-20 nm particle sizes. They have outstanding properties like exceptional biocompatibility, electronic and photoluminescence properties with high surface to volume ratio. GQDs can disperse in water very easily. GQDs energy band gaps can be adjusted by varying their size. GQDs photoluminescence can be changed paralelly with tuning the band gap.

Synthesis and Applications of Graphene Quantum Dots

Graphene Quantum Dots (GQDs) can be synthesized using two primary methods: the Top-Down approach, which breaks down larger carbon sources, and the Bottom-Up approach, using specific organic compounds. Top-Down includes Chemical Oxidation with strong oxidants, the swift Hydrothermal method using high pressure and temperature, the Ultrasound-Assisted method employing sonic force, and the Electrochemical Oxidation leveraging redox voltage. GQDs, known for their compact size and biocompatibility, are used in medicine for enhanced drug delivery. Their unique electrical and luminescent properties also make them ideal for bioimaging, solar cells, LEDs, sensors, and supercapacitors.
