Preparation and in vitro characterization of crack-free mesoporous titania films

► Crack-free mesoporous titanian films (MTFs) with high surface area and pore volume are coated on the Ti6Al4V substrates. ► MTFs improve the apatite-forming ability and biocompatibility of Ti6Al4V. ► The paper will large the application of mesoporous materials in the field of the biomaterials.
