Figure 1 is a simplified version of a process that involves these many players, and lots of
feedbacks between them. However, it is a good way to understand where in the chain, and
how, different barriers emerge between the initial discovery phase, and the eventual entry and
use of a marketable product.
The Central Challenge:
Simultaneously developing useful products for the market, developing the underlying science, and
operationalizing a green nanoscience development and deployment paradigm.
One of the most fundamental challenges particular to green nanotechnology is that the
science, the testing, the regulatory strategy, and even the processes needed for commercial
production are all being developed and deployed at the same time. From this central
challenge flow many early stage challenges that were discussed during the course of the
workshop, including
