The adsorption of environmentally and biologically relevant molecules on the surface of metal oxide nanoparticles can impact the properties of these small particles and thus their behavior. In particular, the impact of surface adsorption of environmentally and biologically relevant molecules from the gas and liquid phase on the properties of nanoparticles in aqueous suspensions (dissolution, aggregation and reaction chemistry) will be presented. Additionally, the role of size, particularly for nanoparticles below 10 nm in diameter, will be discussed. The approach in these studies is to combine nanomaterial characterization using a wide range of techniques including microscopy, spectroscopy, light scattering measurements, along with molecular probes of surface adsorption and surface chemistry to better understand the behavior of oxide nanomaterials in the presence of environmentally and biologically relevant ligands.
