This Handbook draws on contributions from leading nanotechnology regulation scholars around the globe. It goes beyond articulating how certain nanotechnologies are currently regulated and the significance of existing regulatory gaps, to assessing how the future regulatory landscape may evolve. As well as considering potential legislative responses that could be employed by governments, the Handbook examines a range of other options available to stakeholders. The Handbook employs new and innovative lenses through which to view these regulatory challenges and by adopting an in-depth, systematic and whole-of-life-approach, synergistically combines contributions from many countries, many fields and many disciplines. Informative and insightful, it presents thought-provoking and stimulating perspectives on the coming nano-age and on how we as citizens will govern its future.
