Degradable Phosphazene Polymers and Blends for Biomedical Applications

Conference paper
Part of the Advances in Experimental Medicine and Biology book series (AEMB, volume 553)

Abstract

In the biomaterials science, bioresorbable polymeric materials are of great importance in the case of short-term applications that need a temporary presence of implant. It has been known for many years that polymer scaf-folds are useful materials for initial cell attachment and subsequent tissue formation both in vitro and in vivo. A number of requirements should be met for a proper use of polymer scaffolds, such as biodegradability with a con-trollable degradation rate, structure, porosity and surface properties to allow cells to be seeded for a successful growth and differentiation. Mechanical properties comparable to those of the natural extracellular matrices are also desirable.
