TiCaPCON–Ag films with various Ag concentration and redistribution.
Depending on the preparation approach, films demonstrate different Ag+ ion release.
No direct correlation between Ag concentration, Ag+ ion release, and antibacterial properties.
Strong bactericidal effect of TiCaPCON–Ag films.
Bactericide role of Ag nanoparticles on the film surface.
Antibacterial yet biocompatible and bioactive surfaces.
