Polylactic Acid and Polyethylene Glycol Based Biodegradable Polymers

The exploration of polyethylene glycolated (PEG) materials in biosciences and pharmaceutics has grown rapidly. Biodegradable Polymers based on copolymers of polylactic acid (PLA) and polyethylene glycol (PEG) offer scientists new tools for controlled release formulations and delivery platforms.

The biodegradability of polymers based on lactic acid (LA) and its copolymers with ethylene glycol (EG) open new avenues for:

• Encapsulation & Drug Delivery
• Gene Therapy
• Drug Targeting
• Dental & Medical Devices
• Tissue Engineering
• Sutures
• Micellar Anti-cancer Carriers
• Orthopedic Fixation Devices
• Formulation of Artificial Blood Systems
• Determination of Cellular Pathway Mechanisms

As well as offering the following advantages:

• Well defined release process
• Controlled degradation

Polymer structures featuring polyethylene glycol (PEG) segments with biodegradable or biocompatible segments offer micellular, nano and microsphere morphologies which are useful for controlled release formulations.
