The production of phase‐pure, photocatalytically active titania layers at ambient temperature is described. This novel synthesis route has been achieved by using direct‐current reactive magnetron sputtering as well as plasma‐enhanced chemical vapour deposition processes. As a consequence substrates degrading under increased temperature such as, e.g., polymers, biological fibres, tissues, etc., may be coated. The obtained titania coatings are characterised with respect to structure, morphology, phase purity and biological activity. The results of these investigations confirm promising and reproducible photocatalytic, biocompatible as well as bioactive properties.
