Abstract
Methods of enhancing the photostabilizing of silver in medical materials are described. More particularly, the methods increase the photostabilization of silver in certain materials comprising hydrophilic, amphoteric and anionic polymers by subjecting the polymers to solutions containing an organic solvent and silver, during or after which one or more agents are added which facilitate the photostablization of the material.
