A method for preparing bone tissue engineering scaffold using supercritical fluid foaming technology |
| abstract |
The invention discloses a method for preparing a bone tissue engineering scaffold by using supercritical fluid foaming technology. Nucleating agent; wherein, the added amount of the iron oxide particles is 5% to 25% of the mass of the polymer raw material. The invention effectively improves the connectivity and porosity of the prepared stent by adding magnetic iron oxide particles as a nucleating agent in the foaming process, and the added magnetic iron oxide particles do not need to be removed. The magnetic field can accelerate and guide the regeneration of bone tissue in the part of the severed defect. |
