RESOMER® - Biodegradable Polymers for Sutures, Medical Devices, Drug Delivery Systems and Tissue Engineering

Interest in utilizing biodegradable polymers for biomedical applications has grown since the 1960s.

Poly(Glycerol Sebacate) in Tissue Engineering and Regenerative Medicine

The world of commercial biomaterials has stagnated over the past 30 years as few materials have successfully transitioned from the bench to clinical use. Synthetic aliphatic polyesters have continued to dominate the field of resorbable biomaterials due to their long history and track record of approval with the U.S. Food and Drug Administration (FDA).

Biodegradable Polyester Based Nanoparticle Formation by Miniemulsion Technique

Aliphatic polyesters such as polylactide, poly(lactide-co-glycolide) and polycaprolactone, as well as their copolymers, represent a diverse family of synthetic biodegradable polymers that have been widely explored for medical uses and are commercially available.
