Nanotechnology has been applied mostly in the health industry. What could Nanotechnology do for the environment? There is an interesting background article in nanoweek.
Nanoweek News: But scientists working in the comparatively unknown field of environmental nanotechnology argue that working at the nanoscale does not have to be to the detriment of the environment. Studies have shown that nanotechnologies can be used to not only monitor and prevent pollution, but to clean up pollutants once they have already made their way into the environment.
Given policy makers’ increased focus on how emissions can be cut, and the environment protected, the lack of discussion on how nanotechnologies could help is a surprising oversight.
