The Technology Development Pathways workshop showcased application areas where nanotechnology has had commercial impact. Keynote presentations highlighted the pathways companies have taken to get from research to commercialization. Afternoon panel discussions focused on specific steps of the development pathway, such as scale up and quality control/ measurement systems. Building on these successes, conversations at the workshop explored remaining technical challenges or innovations needed to fully exploit the commercial potential of nanotechnology over the coming decades. While the primary focus was to share best practices from the private sector, Federal Government representatives also participated, enabling attendees to learn of ongoing research, agency needs, and funding opportunities. This event supported the goals of the Sustainable Manufacturing: Creating Industries of the Future Nanotechnology Signature Initiative.
