Overview

This approach improves catheter hydrophilicity and reduces CAUTI risks through new antibacterial coatings.

Key Points

  • The modified catheter shows superior antimicrobial efficacy against Staphylococcus aureus and Escherichia coli.
  • Enhanced surface wettability significantly reduces bacteria biofilm formation and patient discomfort.
  • Oxygen plasma activation and polydopamine coating facilitate chitosan grafting on catheter surfaces.
  • This design offers a safer alternative to traditional antimicrobial coatings containing silver nanoparticles.
