What mode of action do nanomaterials ingested via food have in liver and intestine? Which factors determine their toxicity? Due to the large number of different nanomaterials, it is hardly possible to test every one for its toxic properties. For this reason, specific properties for the classification of nanomaterials are to be examined within the scope of the Franco-German research project SolNanoTox, which began on 1 March 2014.

Brightly-colored, iridescent films, made from the same wood pulp that is used to make paper, could potentially substitute traditional toxic pigments in the textile and security industries. The films use the same principle as can be seen in some of the most vivid colors in nature, resulting in colors which do not fade, even after a century.

Nanotechnology, optics and photovoltaic energy are among the fields that can benefit from advances in knowledge on semiconductor nanowire systems. Researchers have succeeded to prove, for the first time, the accumulation of high electron mobility gases in multilayer nanowires from a technique called 'remote doping'.
