Bisphosphonates adsorbed on TiO2 were investigated in this work. Molecules can vary their reactivity according to medium and deprotonation. X-ray photoelectron spectroscopy demonstrated that functionalization occurs in a short time and resulted in a predominantly “side-on” adsorbate configuration after two hours of immersion. The surface is negatively charged due to deprotonated phosphonates, as demonstrated by zeta potential. Molecules adsorb following surface topography, unchanging surface roughness.
