NOM Visible Quantum Dots (QDs) provide narrow band fluorescent emission at wavelengths ranging from 540 nm to 680 nm and are coated with various ligands to achieve water solubility. These CdSe/ZnS core/shell complexes provide higher levels of photoluminescence and stability when compared to core only complexes. Our Water Soluble QDs are coated with a layer of one of three hydrophilic surfactants. Visible CdSe/ZnS quantum dots can be ordered with surfactant coatings that have a terminal group that is either a carboxylic acid, a primary amine, or a diol (two adjacent hydroxyl groups). These groups allow covalent linking to a wide range of (bio)molecules.
