Scientists as well as ,,normal citizens'' need reliable information for a fact based public discussion on the safety of nanomaterials. Unfortunately not all published articles on nanomaterials safety research are suitable for a risk assessment. In consequence it is necessary to separate suitable from not suitable articles to extract reliable information. This is the aim of the project DaNa 2.0, funded by the German Federal Ministry of Education and Research (BMBF), where literature is transparently assessed against a criteria catalogue. Results are published on the project's website.
