Currently practised sterilization methods--some inadvertent consequences

Abstract

Currently used sterilization techniques such as ethylene oxide, gamma irradiation, and steam sterilization could introduce inadvertent consequences, especially in polymeric materials. These could have far-reaching effects on the biocompatibility of the materials. Some of these consequences are reviewed and a typical example of the effect of steam sterilization on the properties and biocompatibility of polyethylene terephthalate is discussed.
