Polymeric quaternary ammonium enabled contact-active, bulk-stable and biocompatible antibacterial catheters for overcoming leaching-dependent antimicrobial additives

Key Points

• The central aim is to develop a catheter that reduces microbial colonization without leaching antibacterial agents.
• Developed catheters using polymeric quaternary ammonium compounds
• Tested durability and biocompatibility of the catheters
• Analyzed antibacterial effectiveness against various pathogens
• The catheters exhibited reduced microbial colonization
• Demonstrated bulk stability without leaching antibacterial agents
• Maintained biocompatibility throughout testing
