Influence of sterilisation methods on collagen-based devices stability and properties

Area of Science:

• Biomaterials Science
• Medical Device Sterilization
• Infection Control

Background:

• Sterilization is critical for implantable medical devices to prevent patient infections.
• Choosing the right sterilization method requires careful consideration of material properties, device characteristics, and potential contaminants.

Purpose of the Study:

• To review the impact of various sterilization methods on collagen-based devices.
• To analyze the effects on structural, biomechanical, biochemical, and biological properties.

Main Methods:

• Review of existing data on sterilization techniques including ethylene oxide, gamma irradiation, e-beam irradiation, gas plasma, peracetic acid, and ethanol.
• Evaluation of the influence of these methods on collagen-based materials.

Main Results:

• Chemical sterilization methods (e.g., ethylene oxide, peracetic acid, ethanol) were associated with cytotoxicity.
• Physical sterilization methods (e.g., gamma irradiation, e-beam irradiation, gas plasma) showed potential for material degradation, influenced by device characteristics.

Conclusions:

• The optimal sterilization method for collagen-based medical devices is highly dependent on the specific device and its intended application.
• Balancing efficacy against material integrity is essential for safe and effective device sterilization.
