Description
Water Soluble Carbon Quantum Dots (528±10 nm)
Water Soluble Carbon Quantum Dots (CQDs) are advanced nanomaterials with excellent aqueous solubility, strong fluorescence, and high biocompatibility. With an emission peak of 528±10 nm (green fluorescence), these CQDs are ideal for a wide range of biomedical, environmental, and optoelectronic applications. Their surfaces contain abundant functional groups such as carboxyl, hydroxyl, and amino moieties, enabling strong dispersibility and easy conjugation with biomolecules like proteins, nucleic acids, and peptides.
Unlike traditional heavy-metal-based quantum dots, Water Soluble Carbon QDs are eco-friendly, non-toxic, and photostable, making them a safe alternative for both research laboratories and industrial production. Their reliable fluorescence intensity, combined with scalable and green synthesis methods, positions them as a cost-effective and sustainable material for next-generation technologies.
