Surface Chemistry in Biomedical and Environmental Science

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 unique 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. This volume holds a special niche in describing the current state of the art in the fundamentals and applications of a variety of nanomaterials.

Recognized leaders in surface chemistry and nanomaterials are contributors A useful mixture of reviews and primary research from leading laboratories A unique blend of East European and Western contributors provides a snapshot of the science of surfaces and nanomaterials
