I recommend that you check out the Nanotort Law Blog.
The Nanotort Law Blog aims to be a useful resource for lawyers and risk managers. It will help you stay abreast of the current state of hazard assessment knowledge, pertinent governmental regulation, industry and NGO standards and guidelines, and other important information germane to environmental, health, and safety risks and potential liabilities. The Nanotort Law Blog will also offer ideas and links to other helpful resources to help you monitor, understand and manage the potential - and as yet unkown - liability risks of Nanotechnologies.
