The influence of surface (nano)roughness of soft elastomeric materials containing nanocrystalline TiO2 on tissue cell behaviour after implantation tests was investigated. Addition of small amount (0.2wt.%) of TiO2into polymer matrix changed surface roughness giving material of well developed lamellar morphology and slightly diminished contact angle (wettability). This lamellar (fibrilar) morphology had strong influence on cell response after implantation into soft tissue indi-cating the absence of eosynophiles in tissue around implant.
