Description and Uses
Amphiphilic polymer or polydiallydimethylammonium chloride (PDDA) coated CdS/ZnS or CdSe/ZnS quantum dots (QDs) do not contain any linkable reactive group on the surface and exhibit a zeta potential of more than +50 mV. These positively charged QDs find applications in cell tracking.
