Nanomaterials and nanoparticles exhibit unique properties which are now being explored for potential uses, as well as hazards. In September 2005 a NATO Advanced Research Workshop convened in Kiev to discuss the current state of the art in surface chemistry and nanomaterials research, with a view towards biomedical and environmental applications. This volume represents the fine work presented at this workshop, consisting of a mixture of reviews as well as primary research articles from leading laboratories in Eastern and Western Europe as well as the US. A common theme throughout much of this volume involves adsorption and interfacial behavior of nanomaterials including core-shell particles, nanoparticles derived from oxides, mixed oxides, carbon, carbon/oxide hybrids, functionalized nanoparticles, polymeric biomaterials, and more. The behavior and design of these nanomaterials for adsorption (or sometimes the lack thereof) of toxins, pollutants, narcotics, warfare agents and various biomolecules are studied with a mix of experimental and theoretical approaches.
