Exceptional Blue Luminescence for Advanced Applications

These hydrophilic graphene quantum dots feature an intense blue emission centered around 440 nm, making them highly suitable for fluorescent probing, bioimaging, and sensory applications. Their robust luminescence under UV excitation enhances signal clarity and detection sensitivity across both laboratory and industrial settings.

Water Compatibility and Biocompatibility

Thanks to their rich surface functionalization (hydroxyl, carboxyl, epoxy), these quantum dots dissolve readily in water and physiological solutions. Their biocompatibilitypaired with low toxicity and eco-friendlinessensures safe use in biomedical research, nanomedicine, and environmentally sensitive applications.

Reliability and Versatile Packaging Options

Packaged in sealed, air-tight containers and available in customizable quantities, these GQDs offer a shelf life of 2 years when stored away from light and moisture. Their stable performance in varied environments guarantees dependable results under laboratory or manufacturing conditions.

FAQs of Blue Luminescent Hydrophilic Graphene Quantum Dots (Powder):

Q: How should Blue Luminescent Hydrophilic Graphene Quantum Dots be stored for optimal stability?

A: These quantum dots should be kept in a cool, dry, airtight container away from direct light to maintain their stability and efficacy. When stored as recommended, they retain a shelf life of up to 2 years.

Q: What are the primary applications of these graphene quantum dots?

A: They are widely used as fluorescent probes in bioimaging, sensors, optoelectronic devices, nanomedicine, and energy storage systems due to their strong blue emission, water dispersibility, and high quantum yield.

Q: When do these GQDs exhibit their strongest luminescence?

A: Their photoluminescence is most pronounced around 440 nm when excited by UV light in the 360380 nm range. This property is optimal for fluorescence-based applications and imaging techniques.

Q: Where can these GQDs be utilized in terms of compatibility and safety?

A: Their hydrophilic nature and biocompatibility make them suitable for application in aqueous environments, biological media, and eco-sensitive contexts. They are also classified as non-poisonous and environmentally friendly.

Q: What is the process for dispersing these GQDs in water or buffered solutions?

A: Simply add the powder directly to the desired aqueous medium and stir; their hydrophilic functional groups enable quick and complete dissolution, resulting in a homogenous quantum dot dispersion.

Q: What benefits do these graphene quantum dots provide over traditional fluorescent markers?

A: Compared to traditional dyes, these GQDs offer stronger photostability, higher quantum yield, lower toxicity, and easier dispersibility in aqueous systems, enhancing reliability in diagnostics and imaging workflows.

Q: How can users request custom packaging or specific quantities?

A: These quantum dots are available in customizable quantities. Customers can contact the supplier or manufacturer to discuss their individual needs and receive appropriately packaged materials according to their project requirements.
