23 Jul Method and equipment for preparing tissue engineering scaffold with anisotropic pore structure
Abstract
The invention discloses a method for preparing a tissue engineering scaffold with an anisotropic pore structure. The method comprises the following steps of: placing polymer solution and porogen into specific equipment; performing heat exchange of subzones by using a plurality of temperature zones and the polymer solution, and precisely controlling the temperature change curves and the heat exchange directions of the polymer solution and the porogen; and fixing the phase separation degree, removing the porogen and solvent and drying. The method can realize precise and controllable anisotropism of the pore structure inside the scaffold by performing the precise and controllable heat exchange of the subzones on the prepared polymer scaffold so as to meet the requirements of tissue engineering application and improve the repairing effect. In addition, the invention also discloses equipment for implementing the method.
