CdS/ZnS core-shell type quantum dots lyophilized, fluorescence λem 450 nm, solid

CdS/ZnS or CdSe/ZnS quantum dots (QDs) with carboxylic acid in lyophilized solid form can readily be reconstituted in DI water or DMSO to any desired concentration and are very stable in most buffer solutions in the pH range of 5-10. These QDs possess zeta potential in -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…
