Here is a page called Project on Emerging Nanotechnologies (via LII). Here is an excerpt from their Mission page:
The Project on Emerging Nanotechnologies was established in April 2005 as a partnership between the Woodrow Wilson International Center for Scholars and the Pew Charitable Trusts. The Project is dedicated to helping ensure that as nanotechnologies advance, possible risks are minimized, public and consumer engagement remains strong, and the potential benefits of these new technologies are realized.
…
Our goal is to inform the debate and to create an active public and policy dialogue. It is not an advocate either for, or against, particular nanotechnologies. We seek to ensure that as these technologies are developed, potential human health and environmental risks are anticipated, properly understood, and effectively managed.
All research results, reports, and the outcomes of our meetings and programs are made widely available through publications and over the web. We include a wide variety of stakeholders, both domestically and internationally, in our work.
We also are committed to engaging a new generation of young people interested in working at the interface of public policy and nanoscience and nanoengineering. We run an active program with university researchers, educators, and students to further that objective.
There is plenty of material to browse through and download; there seem to be a podcast too. Take a look!
