General description

Reactive group: Amine.

Application

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