Interest in nanotechnology is greatly increasing worldwide leading to an extensive research funded each year. The USA and Japan are the leading forces of nanotechnology research, but Europe and other countries are also moving towards this kind of technology due to its increasing demand. The Virtual Institute Vision-On-Line, built upon the present activities of the European Society for Precision Engineering and Nanotechnology, constituted from regional centers in France, Germany and Italy and official national nodes in Spain, Greece, Netherlands, Belgium, Finland and Japan, with a clear focus to “on-line” technical assistance, education and training, addresses a range of “on-line” services to promote industrial growth in the ultraprecision technologies, including ultraprecision engineering, microengineering and microelectronics, microelectromechanical systems, nanotechnology and the support precision technologies, nano and precision metrology. The new and expanding markets of these technologies are demanding miniaturized, more reliable and customized devices at ever-increasing rates and reduced cost.
