Abstract
Materials capable of delivering stabilized free radicals to targeted treatment sites. The materials comprise semi-crystalline, hydrolytically degradable polymers that are subjected to ionizing radiation to create stabilized free radicals therein. Upon exposure to oxygen containing aqueous media, the materials generate reactive oxidative species which are useful in biological processes.
