Duke scientists have discovered a potentially interesting way to deliver drugs from an internal medical device, such as a drug-eluting stent. In research published in the journal Advanced Materials, Xuanhe Zhao, assistant professor of mechanical engineering and materials science at Duke's Pratt School of Engineering, demonstrated that the surface texture of polymers can be altered on demand through application of an electric current.
