A conference on nanotechnology will be held in Germany 30 November-2 December. According to the website:

We convene actors from Germany, Europe, and the United States to link previously separated regulatory debates. Participants will develop regulatory recommendations for German and European politics in frank and open discussions. This includes the prioritization of regulatory approaches and principles to guide the development of compatible regulatory systems on both sides of the Atlantic.

The price is € 160 including accommodation and meals; a reduction to € 80 is available for students. More detail here.
