Overview
Description

Amine-functionalized CdS/ZnS or CdSe/ZnS quantum dots (QDs) find applications in bioimaging and biosensing. The three main conjugation methods reported in the literature are conjugation using glutaraldehyde as a linker, conjugation by using 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) Conjugation with carboxylic acid-containing molecules and direct conjugation with isothiocyanate bearing molecules.
