Microscopic, manmade nanoparticles have found their way into almost every part of our daily lives from clothing, to skin care, our cell phones, and even the soil. But how safe are we from ill effects from extensive exposure? And what happens when engineered nanomaterials find their way into the environment? In this program, experts explore emerging areas of research looking to engineer a healthier, safer, and more efficient future.
PARTICIPANTS: Vicki Colvin, Ponisseril Somasundaran, Paul Weiss
MODERATOR: Andrew Revkin
