Sterilization of Polymeric Implants: Challenges and Opportunities

ACS Appl Bio Mater. 2022 Nov 21;5(11):5077-5088. doi: 10.1021/acsabm.2c00793. Epub 2022 Nov 1.

Abstract

Degradable and environmentally responsive polymers have been actively developed for drug delivery and regenerative medicine applications, yet inadequate consideration of their compatibility with terminal sterilization presents notable barriers to clinical translation. This Review discusses industry-established terminal sterilization methods and aseptic processing and contrasts them with innovative approaches aimed at preserving the integrity of polymeric implants. Regulatory guidelines, fiscal considerations, and potential pitfalls are discussed to encourage early integration of sterility regulatory considerations in material designs.

Keywords: aseptic processing; degradation; oxidative damage; polymeric implant; radicals; swelling; terminal sterilization.
