Scientists use nanotech to prevent heart disease

University researchers have built nanoparticles designed to cling to artery walls and slowly release medicine – a breakthrough that could help fight heart disease.

Scientists at MIT and Harvard Medical School yesterday announced that they teamed up to create what they’re calling “nanoburrs,” nanotechology that sticks to arteries the way that pesky burrs in the woods stick to your clothes. Researchers are hoping the nanoburrs can offer an alternative to surgically implanting arterial stents that, over time, release drugs to treat or prevent plaque build up on artery walls…
