Surface polyPEGylation of Eu3+ doped luminescent hydroxyapatite nanorods through the combination of ligand exchange and metal free surface initiated atom transfer radical polymerization
Surface modification of HAp nanorods through the combination of ligand exchange reaction and metal free SI-ATRP. HAp-polyPEGMA displayed high water dispersibility, good biocompatibility and biological imaging capability. Metal free ATRP can overcome the toxic and fluorescence quenching effects of metal catalysts of conventional ATRP.
