Functional Quantum Dots

Creative Diagnostics provides water-soluble quantum dots with different functional groups, including amine, carboxyl, GSH (glutathione), and MPA (3-Mercaptopropionic acid). GSH or MPA quantum dots have the hydrodynamic sizes of 10-12 nm diameters, while PEG-NH2 and PEG-COOH quantum dots are about 20 nm in size. PEG functionalized quantum dots have much better performance in solubility and pH stability. Amine and carboxyl quantum dots available with a PEG spacer are ideal for covalent conjugation with proteins, antibodies and other biomolecules. Generally, our water-soluble functional QDs have great potential to be used in highly sensitive cellular imaging, molecular recognition and optical devices.
