Biomedical Applications of Biodegradable Polyesters
The focus in the field of biomedical engineering has shifted in recent years to biodegradable polymers and, in particular, polyesters. Dozens of polyester-based medical devices are commercially available, and every year more are introduced to the market. The mechanical performance and wide range of biodegradation properties of this class of polymers allow for high degrees of selectivity for tar...
متن کاملZ-Protected Glutamic Acid-Based Biodegradable Thermoplastic and Thermosetting Polyesters: Synthesis and Characterization
Biodegradable polymers were formed from N-benzyloxycarbonyl-L-glutamic acid with the comonomers ethylene glycol, diglycidyl ether of 1,4-butanediol, and diglycidyl ether of bisphenol A. The three polymers were a linear and a rosslinked heterochain polyester and a crosslinked polyester that contained aromatic units within its network chains. The thermoplastic resin and the soluble fractions for ...
متن کاملSingle crystal morphologies of biodegradable aliphatic polyesters
Single crystals of biodegradable aliphatic polyesters, poly([R]-3-hydroxybutyrate), poly([R]-3-hydroxyvalerate), poly(L-lactic acid), poly( -propiolactone), poly(4-hydroxybutyrate), poly(Æ-valerolactone), poly("caprolactone), poly(ethylene succinate) and poly(tetramethylene adipate), were grown from dilute solution by isothermal crystallization, and the crystal structures and morphologies were ...
متن کاملSynthesis of elastic biodegradable polyesters of ethylene glycol and butylene glycol from sebacic acid.
High molecular weight biodegradable polyesters were prepared from sebacic acid, ethylene glycol and butylene glycol through a simple non-solvent polycondensation with a low toxicity catalyst. The successful synthesis of the polyesters was confirmed by gel permeation chromatography, (1)H-nuclear magnetic resonance and Fourier transform-infrared spectroscopies and differential scanning calorimetr...
متن کاملSurface modification of biodegradable polyesters with fatty acid conjugates for improved drug targeting.
We describe a general method for incorporating target ligands into the surface of biocompatible polyester poly(lactic-co-glycolic acid) (PLGA) 50/50 materials using fatty acids. Avidin-fatty acid conjugates were prepared and efficiently incorporated into PLGA. Avidin was chosen as an adaptor protein to facilitate the attachment of a variety of biotinylated ligands. We show that fatty acid prefe...
