Abstract

We developed a purification strategy for amphiphilic polymer-coated QDs via salting out. Dynamic light scattering (DLS) results revealed that the zeta potential of octylamine-grafted poly-(acrylic acid) (OPA) micelles is closer to zero than that of OPA-coated QDs and can be compressed to electric neutrality first after adding NaCl, inducing the selective precipitation of OPA micelles.
