The Nano Revolution
It’s a universe where scientists explore matter on a scale 80,000 times smaller than a human hair. Nanotechnology promises groundbreaking solutions to the most serious problems that threaten our future, but it’s also a realm that poses serious philosophical, political and ethical questions.

Will Nano Save the Planet?
In the third part of this series from The Nature of Things, meet scientists who believe that nanotech may be the key to overcoming our environmental problems. Nano solar cells could make green energy cheaper. Nano additives to traditional fuels could make them cleaner. Nanotech could remediate contaminated water and soil. But are we creating pollutants more dangerous than the ones we already have? What happens when nano-structured materials decay?
