General description

Reactive group: Carboxylic acid.

Application

The organic layer of the CdS/ZnS or CdSe/ZnS quantum dots (QDs) with carboxylic acid as reactive group consist of a monolayer of oleic acid/octadecylamine and a monolayer of amphiphilic polymer. The total thickness of organic layers on these QDs is approximately 4 nm. They find many applications in bioimaging and biosensing.

Packaging
