Eidgenössische Materialprüfungs- und Forschungsanstalt (EMPA) is a materials science and technology research institution. It belongs to the ETH domain and as such is an important element in education, science and innovation in Switzerland. It specializes in applications, focused research and development, and provides high-level services in the field of sustainable materials science and technology.Its core tasks are innovative collaboration with industry and public institutions, ensuring the safety of people and the environment, knowledge propagation and university-level teaching. The mission of the Materials, Products and the Environment Group (MPE) is to establish the scientific knowledge for a comprehensive and early view of opportunities and risks of applications based on nanotechnology. MPE carries out research on qualitative risk assessment, quantitative modeling (e.g. exposure modeling), release of nanomaterials from products, and behavior of materials in the environment (analysis, reactions and interactions with biota) and considers also socio-economic aspects, e.g. on risk communication and risk governance.
