23 Jul Collagen scaffold with omni-directional through hole structure and preparation method thereof
Abstract
The invention discloses a preparation method for a collagen scaffold with an omni-directional through hole structure. The preparation method comprises the following steps: 1) pouring a collagen solution into a container; 2) putting the container filling with the collagen solution into a refrigerating device and performing gradient refrigeration; 3) putting the collagen refrigerated in step 2) intoa vacuum freeze drier for vacuum freeze drying, thereby acquiring the collagen scaffold with the omni-directional through hole structure. The invention discloses a method for preparing the collagen scaffold with the omni-directional through hole structure by using a micro-needle mold. The collagen scaffold with the omni-directional provided by the invention is beneficial to transferring of nutrient substances in body, is beneficial to immigration and growth of cells and is more suitable for scaffold of tissue engineering.
