DaNa4.0 - advanced materials knowledge base in a new outfit

Introduction After more than 10 years of communicating the risks of nanomaterials in the previous projects DaNa and DaNa2.0, we generally revamped our website www.nanoobjects.info and took the nano experience to expand the portfolio to advanced materials in DaNa4.0. Results Advanced materials represent a group of various smart, innovative materials with new functions and effects. These include materials such as carbon fibres, aerogels and also nanomaterials. They are already used today in a variety of applications such as lightweight plastics with fibre reinforcement or hybrid materials used in 3D printing. Our knowledge base currently contains verified information on more than 26 materials and more than 70 applications. With the help of our literature criteria, we are now evaluating scientific literature on human and eco toxicology of advanced materials and describe the findin gs in a generally understandable way: from a possible exposure to humans, the uptake into the body, to the effect on humans, and from the release of these materials into the environment, their uptake and effect in environmental organisms to the distribution in the environment. We also provide information on the behaviour of advanced materials at the external and internal body barriers of humans. The enormous variety and diversity of advanced materials is a huge challenge for the team of biologists, chemists and toxicologists. Additionally, current topics like labelling of chemicals and additives or nanoplastics in the environment can be found in the section on cross-cutting issues. Conclusions The DaNa knowledge base reliably informs the consumer about potential risks of advanced materials. Scientists will also find results of German projects on advanced materials, SOPs, a SOP template and the literature criteria catalogue for download.
