Visualizing nanotechnology research in Canada: evidence from publication activities, 1990-2009

Over the last two decades the scientific community has witnessed unprecedented growth of nanotechnology research in Canada. Although recent studies have shown that Canada consistently maintains a position in the first tier of productive countries in terms of its share of the world's nano-publications, a number of key questions remain unanswered. Using a unique nano-related publication dataset, this paper combines bibliometric analysis and science overlay mapping to visualize the 'invisible college' of Canadian nano research. The present analysis finds that the rapid growth of nanotechnology research in Canada is, for the most part, externally driven. In recent years, research content has shifted toward nanobiotechnology fields. The geographical distribution of Canadian domestic nanotechnology research is characterized by regional imbalance: most research hubs are located near US-Canadian borders. Canadian nanotechnology scientists have collaborated with a variety of countries, but Chinese scholars in particular play a leading role in Canada's research exchange across national borders.
