Nanoscale Solutions to Gigaton Problem: Exploring Sustainability with Vinayak Dravid

Everyday items like tea bags and sponges are being reimagined in the lab of Northwestern University's Vinayak Dravid, who is using nanotechnology to tackle some of the world's most pressing environmental challenges. In this episode he explains how his team is using nanotechnology to remove toxic metals in water with brewed tea leaves and soaking up oil spills using a special sponge he invented, and many more ways he is leveraging nature's chemistry and nanotechnology to help solve global problems.
