Exceptional Optical Properties

Carboxylated Graphene Quantum Dots offer robust fluorescence, with excitation wavelengths ranging from 350 to 420 nm and emission from 420 to 550 nm. This results in vivid blue to green luminescence, which is highly valuable for imaging and sensor applications. Their excitation-dependent fluorescent response enables customizable visualization in various scientific and diagnostic techniques.


Superior Dispersibility and Stability

These quantum dots are highly dispersible in polar solvents, especially water, due to their carboxyl surface groups. A zeta potential of 30 to 50 mV means they remain stable in suspension, minimizing aggregation. Their shelf life extends up to 12 months when stored at 28C and protected from light, maintaining their optoelectronic attributes over time.


Broad Application Spectrum

Carboxylated Graphene Quantum Dots are widely employed in research, diagnostics, imaging, and as fluorescence markers. Their low cytotoxicity and non-poisonous nature enable use in sensitive biological systems, making them suitable for bioimaging, biosensors, optoelectronics, and targeted drug delivery research. Available as both aqueous suspensions and powders, they meet research-grade standards for diverse scientific needs.
