Abstract
Degradable polymeric biomaterials are preferred candidates for
developing therapeutic devices. Biodegradation of polymeric biomaterials
involves cleavage of hydrolytically or enzymatically sensitive bonds in the
polymer leading to polymer erosion. Amino acids are among the simplest
biomolecules that contain intramolecular hydrogen bonds and they serve as
building blocks of more complex peptides and proteins. Polies (amino acids) are ubiquitous, naturally-occurring biodegradable polymers; however, their
application as a biomaterial has been limited due to immunogenicity and poor
mechanical performances. To overcome these limitations, attempts have been
made to develop amino acids based synthetic polymers. Amino acid based
synthetic polymers are also expected to show biocompatibility and
biodegradability similar to those of polypeptides. Among the synthetic.
