Area of Science:

• Biomaterials Science
• Polymer Chemistry
• Medical Device Sterilization

Background:

• Hydrogels possess valuable biocompatibility, antimicrobial activity, and rheological properties for biomedical applications.
• A significant challenge in using hydrogels for medical applications is identifying sterilization methods that preserve their functional properties.

Purpose of the Study:

• To investigate the impact of conventional sterilization techniques on the physical and chemical characteristics of poly 3-sulfopropyl acrylate potassium (pAESO3) hydrogels.
• To assess the suitability of pAESO3 hydrogels for biomedical applications by evaluating their response to steam, radiation, and gas sterilization.

Main Methods:

• Evaluation of hydrogel swelling degree after exposure to different sterilization methods.
• Assessment of mechanical performance changes in the hydrogel post-sterilization.
• Analysis of chemical effects on the hydrogel structure resulting from steam, radiation, and gas sterilization.

Main Results:

• No significant alterations were observed in the degree of swelling of the pAESO3 hydrogel after undergoing steam, radiation, or gas sterilization.
• The mechanical performance of the hydrogel remained largely unaffected by the tested sterilization protocols.
• Chemical analysis indicated no detrimental effects on the pAESO3 hydrogel's composition due to the sterilization processes.

Conclusions:

• Conventional sterilization methods (steam, radiation, gas) are compatible with poly 3-sulfopropyl acrylate potassium (pAESO3) hydrogels.
• The functional properties of pAESO3 hydrogels, including swelling, mechanical integrity, and chemical structure, are preserved after sterilization.
• These findings highlight the potential of pAESO3 hydrogels as a viable material for various biomedical engineering applications.
