Nanoparticles Target Damaged Blood Vessels
Posted on by Dr. Francis CollinsCardiovascular disease (CVD) is the number one killer of Americans. There are, in fact, many types of CVD—but common to most of them is damaged blood vessels. Stents can be inserted to prop open collapsed or narrowed arteries, and deliver drugs inside vessels. But, so far, we haven’t been able to repair the damaged vessels themselves. Researchers in an NIH-funded team of bioengineers at Clemson University, in South Carolina, are among those who believe that delivering drugs directly to the site of damage to mend the vessel might boost our ability to treat CVDs. And they’ve devised a way to deliver such drugs right where they want them: using specially-crafted nanoparticles.
