Respuesta:
Since the 1920s when Hermann Staudinger pioneered theories on “macromolecules,” covering both natural and synthetic polymers, this concept captured the imagination of chemists to design a wide range of molecular architectures of polymeric materials with fascinating and innovative applications. Polymers were first used in medicine as biomaterials in the 1950s for cornea replacement and as blood vessel replacement. Polymeric biomaterials offer a large diversity as matrix and inclusion materials in the development of biocompatible biostable, biodegradable, or bioresorbable polymeric biocomposite materials for tissue engineering and regenerative medicine applications. Natural polymers are considered as the first biodegradable biomaterials used in biomedical applications
