Assessing emerging technologies - Methodological challenges and the case of nanotechnologies

Technology Assessment reflecting on R&D and technological trends in the area of nanotechnology and its implications is confronted with the problem that most scientific endeavours of nanotechnology can be allocated to basic research while most of the technological visions related to nanotechnology are far (> 10 years) in the future. Since technology assessment has to integrate the socio-economic context of a technical product in order to be comprehensive, in the case of nanotechnology a preparing step is necessary which connects the ongoing basic research with the visions communicated either by the scientist themselves or by the media. In this paper we propose to adapt the well known tool 'roadmapping' to contribute to the solution of this problem. This poses new challenges for roadmapping methodology in terms of level of aggregation and timeframe. (c) 2005 Elsevier Inc. All rights reserved.
