Nanococktails from the laser bar: The production of highly pure nanomaterials by laser ablation in liquids

Abstract:
As measured by the patents in Europe, Nanotechnology is considered as motor for the future of energy, environmental, information and medical technology. Nanostructures have particular properties that differ from those of "the big ones". Nanoparticles of gold, for instance, have a reddish color, ceramic nanoparticles invisibly provide for scratch-resistant car paints, and nanoparticles of silver protect against infections and diseases. Usually, these particles are produced by chemical means in the gaseous or liquid phase, which can lead to agglomerations or impurities by adjuvants such as precursors and additives. For sophisticated applications in plastics and medical technology, however, highly pure and stable particles are required. Furthermore, users often require nanoparticles of new materials and alloys, as well as mixtures of nanoparticles for the combination of nanoeffects. But how can such nanomaterials be produced rapidly and of highly pure quality?
