Surface-Engineered Antibacterial and Anti-Calculus Coatings on Polyester via Chitosan-Amino Acid Grafting and Silver-Ion Coordination

Key Points

• This research aims to develop surface-engineered coatings to prevent bacterial adhesion and calculus formation on polyester materials for medical devices.
• Used chitosan-amino acid grafting to modify polyester surfaces.
• Implemented silver-ion coordination for enhanced antibacterial effects.
• Evaluated the performance of coated surfaces against bacteria and calculus formation.
• The coatings significantly reduced bacterial adhesion compared to unmodified surfaces.
• There was a notable decrease in calculus formation on the modified surfaces.
• Enhanced antibacterial properties were confirmed through testing with relevant bacterial strains.
