CdSe nanoparticles with polystyrene (PS) brushes are obtained by "grafting through" technique starting from solely aqueously synthesized nanoparticles. Mercaptoethanol (ME) capped nanoparticles are used to achieve double bond functional groups on the surface by condensation reaction with methacryloxypropyltrimethoxysilane (MPS). PS
