Welcome to the Nano Revolution.

It's a universe where scientists explore matter on a scale 80,000 times smaller than a human hair. It's a gigantic global laboratory where scientists converge from all disciplines, and dedicate themselves to observing and manipulating the smallest particles in the natural world.

Thirty years ago, new microscopes first opened the doors to this new dimension and allowed scientists to  begin  moving individual atoms and molecules .This science of the miniscule is already  opening up  a new world of possibilities.

Nanotechnology has been called "the next technological revolution". It is said to provide groundbreaking solutions to the most serious problems that threaten our future –it promises faster computers, improved security,  longer healthier lives  and a cleaner earth.
In a series of short dramas, that are interspersed with the documentary content, The Nano Revolution also speculates the philosophical, political and ethical complexities that might arise as the science continues to evolve. How will the new science impact people's lives 30 or 40 years from now?

The Earth's environment faces some great challenges, and it doesn't take much to realize there's no time to waste.  In the third episode of The Nano Revolution, Will Nano save the Planet, we meet scientists who believe that nanotechnology may be the  key to overcoming the biosphere's  environmental problems. Dr Vicki Colvin from Rice University field tests  a  simple low cost technique that could help the developing world clean arsenic out of contaminated ground water . The University of Toronto's Professor Ted Sargent  outlines his research into nano solar cells that would make solar power cheaper and more efficient by capturing  the sun's infrared rays. Professor Peter Dobson from Oxford University,  describes  how adding cerium oxide in nano form to diesel fuel can make it both more efficient and clean up  emissions. At the University of Western Ontario, Dr Dennis O'Carroll  demonstrates nano remediation of contaminated soil .

But are we creating pollutants that are more dangerous than the ones we already have? What happens when nano-structured materials decay?The episode also visits Duke University in North Carolina, where Professor Mark Wiesner's team is investigating the possible environmental impact of silver nanoparticles already being used as anti-bacterial in consumer products. So,will nanotechnology save the Earth's environment? Or will it provide another way in which humans can harm nature?
