The relation between scientific and technological knowledge in emerging fields.:evidence from DNA Nanoscience and DNA Nanotechnology.

To better understand the relationship and interaction between scientific knowledge and technological knowledge, previous studies mainly focused on observing similarities between these two domains. This paper aims to extend our understanding of this relationship by first looking at the interaction between these domains based on the stylised views of science-push and technology-pull, and then detect their similarities, differences, and potential complementaritiesbased on the evolution of their knowledge content. We employed a novel method, called the concept approach for selecting publications and patents in an emerging knowledge field, namely DNA Nanoscience/Nanotechnology, then performed the co-occurrence of terms. Our results not only show that both elements of the stylised ‘science push’ and ‘technology pull’ view can berecognised, but also suggest that co-evolution plays a much more prominent role
