High-Performance Fluorescent Nanomaterial

Blue Luminescent Graphene Quantum Dots (GQDs) deliver strong blue fluorescence with peak emission at approximately 450 nm. Engineered for maximum optical clarity and brightness, these quantum dots ensure precise signal detection in imaging and sensing tasks while maintaining a clear blue appearance in solution.

Hydrophilic and Biocompatible for Bioapplications

Functionalized with -OH and -COOH groups, these GQDs are readily soluble in water and phosphate-buffered saline (PBS). Their low cytotoxicity and high biocompatibility make them ideal for biological applications, including cell imaging and biosensing, without compromising cell viability or experimental safety.

Versatile Solution for Laboratory and Industry

Available in highly stable, sealed packaging (aqueous or powder form), these GQDs serve a diverse range of applications in laboratories, research facilities, and industrial setups across India. Their high purity grade and stability allow for reliable use in analytical, bioanalytical, and optoelectronic projects.

FAQs of Blue Luminescent Hydrophilic Graphene Quantum Dots:

Q: How should Blue Luminescent Graphene Quantum Dots be stored for maximum shelf life?

A: They should be stored in a cool, dry place away from direct sunlight. Sealed vials or bottles under inert conditions are recommended to maintain stability for up to 12 months.

Q: What are the main benefits of using these GQDs in bioimaging and biosensing?

A: The main benefits include excellent water dispersibility, low cytotoxicity, strong blue fluorescence, and high quantum yield, making them ideal for sensitive, non-toxic labeling and detection in biological environments.

Q: When is it best to use the aqueous versus powder form of these GQDs?

A: Use the aqueous solution for immediate applications in aqueous systems or biological experiments. The powder form is preferred for extended storage or when custom dispersion into different solvents is required.

Q: Where can these quantum dots be applied in industrial and research settings?

A: They are suitable for laboratories, research institutions, and industrial applications such as optical sensors, bioimaging, fluorescence-based labeling, biosensing, and optoelectronic device development.

Q: What process is used to synthesize these graphene quantum dots?

A: A top-down approach is employed, involving acid exfoliation or oxidative cutting to produce nanoscale sheet fragments with controlled size and luminescence properties.

Q: How do the surface functional groups enhance the usability of these quantum dots?

A: The hydrophilic -OH and -COOH groups promote high solubility in water and PBS, simplify bio-conjugation, and facilitate biocompatibility for biological experiments or analytical procedures.

Q: What is the typical pH of the graphene quantum dots solution, and why is this important?

A: The pH typically ranges between 6.8 and 7.2, ensuring neutral conditions that support compatibility with a variety of biological and analytical applications without altering sample integrity.
