| Research Abstract |
Global knowledge structure of nanotechnology including interaction between nanotechnology and other technology was studied. The map of totally 27,000 patent applications linked by backward and forward citations was generated.
Analysis on the linkages among the domains showed that the knowledge flows between domains were still small even non-nanotechnology patent applications were included in the analysis. Diversity of knowledge is likely encapsulated in the domains and interdisciplinary in nanotechnology is achieved in the each domain rather than among the domains in the present case.
Diversity is high especially in domains related to "Nanomaterials." Interaction between nanotechnology and other technology varies across the domains. It was shown that the ratio of nanotechnology applications and gap in the average publication years in the domains were useful indicators to characterize the domains.
