Surface modification of titanium dioxide (TiO2) nanoparticle is essential to control its surface properties, thereby to enhance its cell penetration capability, reduce its cytotoxicity, or improve its biocompatibility. In order to graft polyvinyl acetate onto TiO2 nanoparticles, xanthate was chemically immobilized on the surface of TiO2 by acylation followed by nucleophilic substitution with a ...
