Although nanotechnology is in its infancy, their is an overall agreement about the need of dialogue between scientists, the industry and the public about risks and benefit of nanotechnology. The Federal Institute for Risk Assessment (BfR) in Germany supports this strategy by own dialogue activities. These activities base on participation and favour the dialogue with stakeholders and the general public. In 2006, the BfR proactivly organized two dialogue projects – an Expert Delphi Survey and a Consumer Conference - in order to detect risks of nanotechnology in consumer-relevant areas like foods, cosmetics and textiles. Also expert talks and stakeholder meetings are arranged by the BfR to handle acute risks for consumers caused by nanotechnology products (“Magic Nano”). The new risk communication strategy of the Federal Institute for Risk Assessment and objectives, methods and outcomes of the nanotechnology dialogue activities will be described.
