Description
Water Soluble Carbon Quantum Dots (515±10 nm)
Water Soluble Carbon Quantum Dots (CQDs) are advanced fluorescent nanomaterials designed for high solubility, bright emission, and excellent compatibility with biological systems. With an emission peak at 515±10 nm (green fluorescence), these CQDs provide stable luminescence, photostability, and eco-friendly composition, positioning them as a safe and sustainable alternative to heavy-metal-based quantum dots.
Their surfaces are enriched with carboxyl, hydroxyl, and amino groups, allowing easy conjugation with biomolecules such as proteins, DNA, and enzymes. This functional versatility makes them highly effective in biomedical imaging, biosensors, environmental monitoring, and therapeutic platforms. Due to their low cytotoxicity, Water Soluble CQDs are especially suited for in vivo applications, supporting research in drug delivery and targeted therapies.
At Nanographenex, we supply high-purity CQDs with controlled particle size and morphology, ensuring reliable performance in both academic research and industrial applications. Their eco-friendly synthesis, combined with scalable production, makes them a cost-effective nanomaterial for next-generation science and technology.
