SEM image at a tilting angle of 45 degrees show the typical patterns of the nanostructures at the noble metal stent surface obtained with the new FZD technology.
SEM image at a tilting angle of 45 degrees show the typical patterns of the nanostructures at the noble metal stent surface obtained with the new FZD technology.

Stents are medical implants that, for example, prevent the blocking of arteries after surgery. One of the problems using stents is the biocompatibility as the human body rejects and attacks foreign material. The Forschungszentrum Dresden-Rossendorf (FZD) developed a new method for making the surface of metal stents highly nano porous by producing millions of nano bubbles underneath.
