In recent years, questions about democratic influence on science and technology have received much attention. The lesson from the European unrest over GMO is that consumer-citizens will react negatively to being forced to accept the introduction of new, partly untested technologies. A number of political bodies have started to involve citizens and to consider their concerns, attitudes, hopes, and worries in the early stages of the coming nano revolution. This volume is assembles the contributions of experts who analyze a number of these deliberations, mainly in the European Union and the United States. The book analyzes citizen-oriented deliberations along with more stakeholder-oriented deliberations.
