Water Soluble Cd Free Quantum Dots

Cd Free Quantum Dots are composed of CuInZnS cores surrounded by a shell of ZnS and are offered as an alternative to Cd based quantum dots (QDs) where potential toxicity is a concern.  Three different water soluble forms are coated with hydrophilic surfactants to achieve dispersion in water. The three different water soluble forms have surfactant terminal end groups that are either a carboxylic acid (-COOH), a primary amine (-NH2), or a diol (-CHOH-CH2OH). These Cd free QDs provide the high brightness, strong optical absorbance over a wide excitation wavelength range, and photostability characteristic of all quantum dots. Pricing begins at $299 for 10 mg.
