Nanotechnology produces engineered nanomaterials (ENMs) that have new or enhanced physico-chemical properties in comparison to their micron-sized counterparts. Some of these properties, like a high surface area to volume ratio, make them very interesting for technological applications but at the same time make them potentially dangerous to humans as shown by research in the field of nanotoxicology.
To promote the development of a new generation of ENMs that are ‘safe-by-design’, an understanding of the relationship between ENM structure and biological activity is needed. In this context, the Quantitative Nanostructure-Toxicity Relationships (QNTR) computational modelling technique is an effective alternative to experimental testing since it enables the prediction of (eco)-toxicological effects based on ENM structure only. The construction of the QNTR model requires the integration of expertise from nanomaterial scientists, (eco)-toxicologists, and modellers from academia, regulatory agencies and industry.
MODENA, an Action of the intergovernmental European research framework COST, will promote the coordination of inter-disciplinary collaborations of different parties with the ultimate aim of producing QNTR models for ENMs. The results will include:
