23 Jul Method and device for preparing electrospinning fiber bracket with three-dimensional structure
Abstract
The invention discloses a method and device for preparing an electrospinning fiber bracket with a three-dimensional structure. The preparation device can be used for generating a body form electric field and directly preparing a three-dimensional electrospinning fiber bracket in the electrostatic spinning process. The preparation method has a simple process and low cost, and is suitable for preparing three-dimensional electrospinning fibers of different chemical strengths, biocompatibilities and degradation properties by using different spinning materials. The three-dimensional electrospinning fiber bracket has the advantages of capability of allowing seed cells enter the bracket smoothly, realization of in-vitro three-dimensional culturing and tissue engineering repair of the seed cells, contribution to the adhesion growth of the cells, conveying of nutrient substances and discharge of metabolic wastes, facilitation of the proliferation, growth and differentiation of the cells in the bracket, increase in the survival rate and breeding speed of the cells, establishment of a good metabolic environment for the growth and proliferation of the cells, contribution to the breeding of the cells and healing of tissues, suitability for cell three-dimensional culturing and large application value in the field of tissue engineering.
