Medical implants often carry surface substrates that release active substances or to which biomolecules or cells can adhere better. However, degradable gas phase coatings for degradable implants, such as surgical suture materials or scaffolds for tissue culturing, have been lacking so far. In the journal An-gewandte Chemie, researchers of Karlsruhe Institute of Technology now present a polymer coating that is degraded in the body together with its carrier.
