Biodegradable Polymers and their Role in Drug Delivery Systems

Abstract

Biodegradable polymers are currently limited in their application in engineering of soft tissues because they are too stiff and incompliant. Biodegradable elastomers overcome these limitations; they have ability to recover from multiple deformations. Citric Acid based Biodegradable Polymers (CABEs) are a family of elastomers that have been recently developed. Further developments in this area are still needed but they provide a promising new material that can be used for drug delivery systems.
