ABSTRACT:
The invention features a method of treating polyester material to generate functional carboxylic acid and amine groups. These functional groups can be used as sites for covalent bond formation to attach chemical or biological moieties. This bifunctionalized polyester polymer can be used in any medical application in which biocompatible polymers are used.
