title: Preparation and characterization of a novel porous titanium scaffold with 3D hierarchical porous structures.
abstract: This study aims to prepare a novel porous titanium (Ti) scaffold in order to improve the biocompatibility of the metallic implants. Porous Ti was produced by a Liquid foaming method and subsequent chemical treatments. It was found that the scaffold had three-dimensionally hierarchical porous structures with pore size ranging from nanometer to micrometer scale, and it also had activated surface. Mechanical test results showed that the scaffold also has sufficient compressive strength to meet the requirements of implantation. Protein adsorption results indicated that the novel scaffolds significantly enhanced the protein adsorption.
