The purpose of this Technology Foresight on nano-technology was to provide knowledge regarding the scope for nano-scientific and nano-technological developments over the next 20 years, as a basis for the development of a cohesive, long-term policy for research, education and innovation in this area. The delivery of an action plan for Danish nano-science and nano-technology containing recommendations for the next few years was the most essential task in the project. The target group consisted of the Danish Ministry of Science, Technology and Innovation and the Danish system of advisory and grant-awarding bodies for research and innovation.
