General description

Reactive group: Carboxylic acid.

Application

CdS/ZnS or CdSe/ZnS quantum dots (QDs) with carboxylic acid in lyophilized solid form can be readily reconstituted in DI water or DMSO to any desired concentration and are very stable in most buffer solutions with a pH range of 5-10. These QDs possess a zeta potential in the -30 mV to -50 mV range and can easily be reacted with amine containing molecules in DMSO or water. These QDs find applications in bioimaging and biosensing.
