U.S. lead researchers from MIT and Harvard University have developed nanoparticles called nanoburrs that attach to damaged arteries and release medicine to open clogged arteries and repair injured ones. The new nanoparticles could vastly improve the repair and treatment of such cardiovascular problems in humans.
Engineers from Monash University (Victoria, Australia) have
built a miniature mechanical motor for a microbot that could someday
cruise through miniscule human arteries of the brain, heart, and eyes.
