Zn-DLC films with bone formation-promoting effects were fixed in vivo in living mice. After a set period, the films were retrieved to investigate structural changes in the Zn-DLC films due to Zn elution. X-ray absorption fine structure measurements using synchrotron radiation revealed that Zn in the Zn-DLC films exists as a metal and remains unchanged even after Zn elution. Furthermore, Measurements using positron annihilation spectroscopy with a low-energy positron beam confirmed an increase in the free volume within the Zn-DLC film.
