Description
Water Soluble Carbon Quantum Dots (420±10 nm)
Water Soluble Carbon Quantum Dots (CQDs) are advanced nanomaterials with high fluorescence, excellent water dispersibility, and remarkable biocompatibility. Unlike traditional heavy-metal-based quantum dots, these CQDs are eco-friendly and non-toxic, making them ideal for both biomedical and environmental applications. Their surface is enriched with functional groups such as carboxyl, hydroxyl, and amino moieties, which not only improve solubility in aqueous environments but also enable easy conjugation with biomolecules like proteins, nucleic acids, and peptides.
With a strong and stable emission at 420±10 nm, Water Soluble CQDs are widely employed in fluorescent probes, medical diagnostics, sensors, and energy-related technologies. Their robust photostability, low cytotoxicity, and sustainable synthesis routes further position them as a cost-effective and scalable material for next-generation research and industrial applications.
