Effective surface-functionalization of inorganic nanoparticles is important for targets that require tailored solubility and miscibility of the particles. Polymers are particularly useful in this regard, as polymer coverage of nanoparticles can provide an effective method to prevent nanoparticle aggregation and degradation. Here we describe a grafting-from copolymerization process that is effective for encapsulation of both CdSe quantum dots and Au nanoparticles. Key to this method is the integration of cross-linking functionality into the copolymer grafts. We apply this cross-linking method to the encapsulation of CdSe quantum dots and gold nanoparticles.
