Abstract
The Organisation for Economic Co-operation and Development (OECD) estimates that in 2015 the worldwide nanotechnology-related market will reach about US$1 trillion and will create about two million additional jobs. The field began with the general technical industry, including many areas of the pharmaceutical, medical, agricultural, and environmental/energy industries, and recently has expanded to the formulation of nanotechnology. In particular, elements of nanometer-sized research and development (R & D) in the areas of drug delivery systems and nanomedicine are attracting widespread interest. On the other hand, the potential negative effects on human health and the environment of nanomaterials manufactured on the industrial scale have not been investigated in detail. Therefore, although the risks have not been fully clarified, research institutions and international organizations such as the OECD are working in earnest to elucidate them. This paper outlines the status of initiatives in industry and regulatory conditions and trends in individual countries and institutions to determine the safety of nanomaterials from the perspective of international relations.
