Near Infrared CdSeTe/ZnS Quantum Dots – Water Soluble

$299.00 – $1,371.00

Ranging in narrow band fluorescent emission wavelengths from 700 nm to 880 nm, NOM  near infrared water soluble quantum dots are highly luminescent CdSeTe/ZnS core/shell complexes. They are coated with hydrophilic surfactants to achieve dispersion in water. Our 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).  Prices start at $299 for 10 mg.

Description

Water soluble Near Infrared (NIR) Quantum Dots are used for in vivo bioimaging because they have greater sample penetration depths and excite less autofluorescence as illustrated in our graphic. Ranging in  fluorescent emission wavelengths from 700 nm to 880 nm, NOM  NIR water soluble quantum dots are highly luminescent CdSeTe/ZnS core/shell complexes.  These quantum dots are surface 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 coatings allow covalent bonding of the QDs to a variety of molecular probes and surfaces for many fluorescent labeling applications.
