At 10,000 times smaller than the width of a human hair, you can't see nanoparticles, but you can find them in everyday products like sunscreen and clothing. But environmental and health concerns are mounting about exposure to nanomaterials, sparking a growing debate about their possible regulation. QUEST looks further into nanotechnology, as this rapidly expanding field begins to play a larger part in our lives.
What's 100,000 times thinner than a strand of hair? A nanometer. Discover the nanotech boom in Berkeley, where researchers are working to unlock the potential of nanoscience to battle global warming and disease.
