The document summarizes the Swiss scientific initiative Nano-Tera.ch, which funds research at the intersection of micro- and nanotechnologies for health, security, and environmental applications. It has allocated 120 million Swiss francs to support over 600 researchers across 30 institutions through 52 projects in three categories: research, technology, and development projects; focused projects; and education and dissemination activities. The initiative is planned to continue in a second phase from 2012-2016 with a focus on integrating new technologies into systems and demonstrating applications, and a third phase from 2017-2020 to consolidate results.
