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.

Welcome to Nano City
In the first part of this series from The Nature of Things, find out how the invisible revolution of nanotechnology is already at work in our lives — from photocatalytic window coatings that clean themselves to manmade nano fibre stronger yet lighter than steel. Then look to the future of nano in the ultimate miniaturized computer, tags that minutely track consumer goods and an ambitious project to build artificial neural systems.
