As scientists and technologists discover how to engineer matter at the nanoscale in increasingly sophisticated ways, conventional approaches to ensuring safe use are being brought into question. Nanotechnologies are challenging traditional regulatory regimes; but they are also prompting new thinking on developing and using emerging technologies safely. In this Handbook, leading international authors from industry, government, non-governmental organisations and academia examine the complex and often controversial regulatory challenges presented by nanotechnologies. Across several disciplinary...
