Smoothly Tunable Surface Properties of Aluminum Oxide Core−Shell Nanoparticles By A Mixed-Ligand Approach

Luis Portilla and Marcus Halik Abstract We present a facile solution-based procedure for tailoring the surface properties of aluminum oxide nanoparticles (AlOx-NPs) by the formation of tunable core–shell systems with self-assembled monolayers. By employing chained molecules with a phosphonic acid anchor group and either hydrophobic or hydrophilic chains the surface properties of the nanoparticles change […]
