Descripción general

Reactive group: Carboxylic acid.

Aplicación

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.

Dr. Delehanty and researcher introduce recent advances in the use of cadmium-free quantum dots for bioimaging. Focus is placed on strategies that have emerged in the last five years for design, synthesis, and surface modifications of non-Cd quantum dots (QDs) for bioimaging and sensing applications.
