Synopsis Nanotechnology is the minisaturisation of technology to the billionth of a meter (the nanometer) to the molecular level. It is the design and manufacturing of intelligent miniature machines, programmed to perform specific tasks. Nanoscience and technology are emerging arenas of research and development with tremendous potential to improve the human condition along with some real possibilities of significantly worsening mankind’s situation. The emergence of nanoscience portends a revolution in technology that will soon impact virtually every facet of our technological lives. Yet there is little understanding of what it is among the public and often among scientists and engineers in other disciplines. The present publication is an introductory text on manotechnology, covering all basic aspects, including molecular nanotechnology, nanomaterials, nanopowders, nanoelectronics, optics, photonics, solar energy and nanobiomimetrics. It provides a scientifically sound treatment accessible, students and all who are interested in ‘the technology of the future’.
