The Project on Emerging Nanotechnologies (PEN) at the Woodrow Wilson International Center for Scholars hosted on October 9, 2007, a seminar on the Responsible NanoCode, a voluntary, principles-based Code of Conduct for entities involved in the research, development, manufacture, and retail sale of products using nanotechnologies. The draft Code was developed by a working group organized in late 2006 by The Royal Society, the United Kingdom’s (UK) national academy of science, in conjunction with Insight Investment, the Nanotechnology Industries Association (NIA), and the UK government-sponsored Nanotechnology Knowledge Transfer Network.
