Abstract
This contribution discusses the United Kingdom (UK) government’s regulatory activities related to nanotechnological development. The central question is what other prudent public regulation can learn from the UK government’s regulatory strategy, its regulatory attitude and its large variety of regulatory measures. Other public regulators can learn from the interactive and integrative UK regulatory approach. They can also draw lessons from the critique on the UK government’s regulatory attitude and its problems to cope with specific nanotechnological challenges. These lessons are based on an evaluation of the UK government’s regulatory activities from the viewpoint of prudent regulation. The notion of responsive regulation, which provides basic ideas for the evaluation methodology, refers to a view on prudence that focuses on moral constitutional values. Interestingly, a similar view on prudence has been discussed in nanoethics.
