Application-safe and environmentally friendly development and use of nanomaterials

(BfR Federal Institute for Risk Assessment) Thus BfR researchers have found out that pure silver nanoparticles are, following simulated digestion in the stomach and intestine, absorbed in much lower quantities than particles which are digested together with food components. This means that studies based on the pure substance without the food components can lead to a situation where the risks are not assessed correctly.
