| titleOfInvention | 3D printing porous titanium surface antibacterial and osteogenesis promoting controllable drug release system and preparation method |
| abstract | The invention relates to a controllable drug release system for 3D printing porous titanium surface antibiosis and osteogenesis promotion and a preparation method thereof, the structure comprises a double-tube-diameter nanotube film layer obtained by PDA modified anodic oxidation, the upper layer is a small-tube-diameter layer which is used as an interface interacting with cells and a 'valve' for drug release; the lower layer is a large-diameter layer used for loading medicines. Firstly, electrolyzing a porous titanium double-tube-diameter nanotube printed by 3D to obtain a double-tube-diameter nanotube film, and adding a zinc ion load and an antibacterial peptide load. The invention can construct a controllable drug release system based on the double-tube-diameter titanium dioxide nanotube on the surface of the porous titanium base, thereby greatly improving the practical application of titanium and titanium alloy in the aspects of hard tissue implantation, drug carriers and the like. |
