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.

FAQs of CARBOXYLATED GRAPHENE QUANTUM DOTS:

Q: How should I store Carboxylated Graphene Quantum Dots for optimal stability?

A: Store the quantum dots at 28C in tightly sealed HDPE bottles or glass vials, protected from light. This ensures up to 12 months of shelf life and preserves their optical and dispersibility properties.

Q: What is the primary advantage of the carboxyl functionalization on these graphene quantum dots?

A: Highly carboxylated (COOH) surfaces improve water solubility and facilitate functionalization for bioconjugation. This enhances compatibility with biological systems and broadens their application in biosensing and bioimaging.

Q: When are Carboxylated Graphene Quantum Dots most effectively used in research?

A: These quantum dots excel in fluorescence-based applicationssuch as imaging, sensors, and diagnosticsparticularly when stable, bright, and excitation-dependent emission is required. Their low cytotoxicity allows use in cellular and molecular studies.

Q: Where can these quantum dots be applied within the research and diagnostic field?

A: They are widely used in laboratory research, clinical diagnostics, optoelectronic studies, and drug delivery systems, owing to their strong fluorescence, stability in polar solvents, and biological compatibility.

Q: What process is followed to utilize these quantum dots in bioimaging?

A: The quantum dots are dispersed in aqueous or buffered solutions and introduced to the biological sample. Their bright fluorescence under UV/visible excitation enables high-contrast visualization of cellular or molecular targets.

Q: What are the main usage benefits of Carboxylated Graphene Quantum Dots over other nanomaterials?

A: They offer strong and tunable fluorescence, excellent dispersibility, high purity, and low cytotoxicity. These features make them highly reliable for sensitive analytical techniques in both biological and materials sciences.
