Click-based thiol-ene photografting of COOH groups to SiO 2 nanoparticles: Strategies comparison

We present the study of the anchoring of carboxylic groups on SiO 2 nanoparticles from different approximations based on the photochemical radical thiol-ene addition (PRTEA) reaction: a photografting approach between mercaptosuccinic acid (MSA) and vinyl-modified SiO 2 nanoparticles and the post-gra...
