Overview

Description

Our cadmium-based near-infrared water-soluble quantum dots with narrow-band fluorescence emission wavelengths ranging from 700 nm to 880 nm are highly luminescent CdSeTe/ZnS core/shell complexes. These quantum dots are coated with a hydrophilic surfactant to enable dispersion in water. Three different water-soluble forms have surfactant end groups, which are carboxylic acids (-COOH), primary amines (-NH2), or diols (-CHOH-CH2OH). These coatings allow QDs to be covalently bonded to various molecular probes and surfaces for many fluorescent labeling applications.
