What are the Common Techniques for Scaffold Fabrication?
Several techniques are employed for scaffold fabrication, each with its advantages and limitations:
Electrospinning: This technique uses an electric field to draw thin fibers from a polymer solution, creating a fibrous scaffold that mimics the natural ECM. 3D Printing: Allows for the precise layer-by-layer construction of scaffolds with complex geometries and customized architectures. Self-Assembly: Utilizes the inherent properties of molecules to organize themselves into structured networks. Phase Separation: Involves separating a polymer solution into different phases to create a porous scaffold structure.
