Abstract

Quantum dots (QD) were successfully coated with an amphiphilic block copolymer (PS250-b-PAA13) with a diameter of ca 30 nm. The fluorescent properties were preserved even after the encapsulation, resulting water-soluble QD. The glassy, block copolymer surfactants enhance the stability of QDs against extreme environments, and may contribute to the use of QDs in biological or biotechnological protocols requiring these conditions.
