This systematic review evaluates copper-containing materials for soft-tissue biomedical devices, analyzing 65 studies on their surface modification and biological performance. The findings indicate that moderate copper incorporation enhances antibacterial efficacy while maintaining hemocompatibility, but excessive copper can lead to corrosion and adverse cellular effects. The review highlights the potential of multifunctional copper-based coatings for improved device performance.
Key findings
- Antibacterial performance is strongly influenced by copper concentration and ion release profiles.
- Moderate copper incorporation improves antibacterial efficacy while ensuring acceptable hemocompatibility.
- Excessive copper loading can accelerate corrosion and induce negative cellular responses.
- Multifunctional architectures can enhance antibacterial, antithrombotic, and proendothelial effects.
Why it matters
Understanding the balance between antibacterial efficacy and cytocompatibility in copper-based materials is crucial for developing safer and more effective biomedical devices. This knowledge can guide clinicians in selecting materials that optimize patient outcomes in soft-tissue applications.
