Medical implants often carry surface substrates that release ac-tive 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 tis-sue culturing, have been lacking so far. In the journal An-gewandte Chemie, researchers of Karlsruhe Institute of Technol-ogy now present a polymer coating that is degraded in the body together with its carrier.
