This talk will focus on the adsorption of environmentally and biologically relevant molecules on the surface of metal oxide nanoparticles. The application of ATR-FTIR spectroscopy to study surface adsorption, delineate surface structure, quantify surface coverage and determine thermodynamic equilibrium constants is shown.  Furthermore, because surface adsorption changes surface charge and hydrophobicity, it will alter nanoparticle interactions with natural and engineered interfaces, as will be discussed.
