Description
NOM Indium Sulfide Quantum Dots (QDs) are tuned to provide fluorescent emission in the visible region of the spectrum (520 nm to 640 nm) at 20 nm intervals. These QDs provide an alternative to more toxic Cadmium based QDs for many applications. The InP/CdSe/ZnS core/shell QDs have high Quantum Yields (brightness) with narrow bandwidths varying from 40 nm to 65 nm, increasing with fluorescent emission wavelength.
Three different water soluble forms are available. All 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 amine (-NH2), or a diol (-CHOH-CH2OH). These coatings allow covalent bonding of the QDs to a variety of molecular probes for many fluorescent labeling applications. The following water soluble CuInZnS/ZnS core/shell Quantum Dots are in stock in the acid, amine, and diol coated forms. Pricing begins at $299 for 5 mg.
