Research trends in nanotechnology studies across geo-economic areas

The purpose of this paper is to analyze the current temporal and spatial research trajectories in nanoscience and nanotechnology studies in order to display the worldwide patterns of research fields across main economic players. The results show the leadership of Europe and North America in nanotechnology research, although the role of China has been growing over time. Current nanotechnology studies have been growing in chemistry and medicine because of applications of nanomaterials mainly in Chemical Engineering, Biochemistry, Genetics and Molecular Biology. Results also show a relative higher scientific performance in nanotechnology research production by South Korea in comparison with Japan and other geo-economic areas. This research can provide vital findings to support research and innovation policies aimed at improving the development of this technological system for modern patterns of economic growth.
