Blood-repellent materials: A new approach to medical implants

Medical implants like stents, catheters and tubing introduce risk for blood clotting and infection — a perpetual problem for many patients. Engineers now offer a potential solution: A specially grown, ‘superhemophobic’ titanium surface that’s extremely repellent to blood. The material could form the basis for surgical implants with lower risk of rejection by the body.
