Blood-repellent metal could lead to safer implants
If you have to get an implant in the future, you may not have to worry quite so much about your body rejecting that life-enhancing technology. Colorado State University scientists have developed a titanium surface that's so blood-repellent that it fools your body into believing that there's no intruder at all. The team grew chemically modified layers that serve as barriers between the metal and organics, blocking any real contact. Fluorinated nanotubes were the most effective method of repelling blood in the experiments.
