Nanotechnology has its origin in the converging abilities of physics, chemistry and materials science. Its purpose is the manipulation of atoms and molecules in order to create new properties of materials and systems for a wide variety of applications in a very broad range of sectors. Nanotechnology is forecast to create large markets and many new jobs and may be the springboard for industrial renewal and long-term growth. Governments around the world have targeted this emerging technology in their R&D investments and are strategising about the best ways to promote the responsible development and use of nanotechnology given the absence of any in-depth analysis of its commercialisation. What are the potential economic impacts of nanotechnology, how are companies using nanotechnology for innovation, and what are the key challenges in its commercialisation? These are some of the issues that this book addresses, based on a large number of company case studies in several countries.
