Material is Bloody Slippery
A new slippery material for medical devices prevents blood from sticking and causing problematic clots.
Blood tends to clot when exposed to foreign objects and the environment outside of the body, which, by and large, is a very positive phenomenon. But in modern medicine, there are many occasions when clotting can interfere dangerously with the operation of things like heart-lung devices or dialysis machines. Dr. Ben Hatton from the Departments of Materials Science and Engineering at the University of Toronto, and his colleagues, have developed a technology that uses a liquid layer attached to a treated surface that is remarkably slippery. Blood slides right off it, so clots tend not to form, which makes it potentially useful for a range of medical devices.
