Antibacterial Amino Acid-Based Poly(ionic liquid) Membranes: Effects of Chirality, Chemical Bonding Type, and Application for MRSA Skin Infections

Bacteria induced infection remains a serious medical hazard to humans. Antibacterial polymeric materials, which can kill or inhibit bacteria by disrupting cell membranes, inhibiting certain enzymes, or interfering with the transcription or synthesis of DNA or RNA, have been applied to reduce or inhibit microbial drug resistance. Herein, amino acid-based ionic liquids (ILs) and poly(ionic liquid) (PIL) membranes were synthesized and used as antibacterial materials to treat skin wounds infected by methicillin-resistant
