The survey on the research trend for nanotechnology

나노기술에 대한 연구개발 동향 조사

Nanotechnology arises from the exploitation of physical, chemical,and biological properties of systems that are intermediate in size between isolated atoms/molecules and bulk materials, where phenomena length scales become comparable to the size of the structure. In addition nanotechnology implies direct control of materials and devices on molecular and atomic scale, including fabrication of functional nanostructures with desired properties, synthesis and processing of nanoparticles, self-assembly, use of quantum effects, etc. This article is a collection of Informations of trend of research and development in the field of nanotechnology in U.S., EU, Japan and Korea. And we would like to include some idea to decide the direction and the strategy for the investment for nanotechnology.
