CAN NANOTECHNOLOGY STOP A BULLET?
The bullet flies at the police officer at about 3,300 feet per second. At this speed even a Kevlar vest would be pierced, making the shot deadly. But the officer does not die— instead, the projectile merely bounces off of his chest and falls to the ground. This was made possible by nanotechnology: Researchers at the Massachusetts Institute of Technology (MIT) are developing a bulletproof fabric that’s just 20 nanometers thick and can even withstand heavy machine-gun fire. The material is hard as steel, yet it’s considerably lighter than regular body armor. If a bullet does penetrate the suit, the nanolayers will automatically release medicinal substances.
