Nitric oxide releasing vascular catheters for eradicating bacterial infection

20-Dec-2017 | Jitendra Pant, Marcus J. Goudie, Sarah M. Chaji, Benjamin W. Johnson, Hitesh Handa, Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2017

Abstract The interaction of blood proteins with an implant surface is not only a fundamental phenomenon but is also key to several important medical complications. Plasma proteins binding on the surface of intravascular catheters can promote bacterial adhesion leading to the risk of local and ...

Rethinking digital manufacturing with polymers

15-Dec-2017 | Justin Poelma; Jason Rolland, Science , 2017

Additive manufacturing (AM) is poised to radically change the way objects are manufactured, ranging from critical applications such as aircraft components and medical devices to more commonplace, yet highly engineered, products such as running shoes. The ability to produce three-dimensional (3D) ...
