Project TitleNanoporous Biodegradable Thermoset Elastomers
Track Code2007-070
Short Description

Novel citric acid polymers and their use in controlled therapeutic delivery systems.


Northwestern researchers have developed novel citric acid polymers and their use in delivery systems. For this invention, investigators in Guillermo Ameer's laboratory have created elastomeric citric acid polymers onto which biologically active molecules may be attached. The synthesis of the polymers requires polyethylene glycol dimethyl ether (PEGDM), and its pores range in diameter from 7 to 15 nanometers. This technology offers controlled delivery of bioactive molecules, proteins, and drugs.
