Objective:
To review recent advances in cationic antimicrobial systems - including surfactants, polymers, peptides, quaternary ammonium-based materials, and ionic-liquid-derived agents - and to summarize emerging strategies aimed at combating antibiotic-resistant bacteria.
Significance Of Review:
Cationic antimicrobial compounds provide a promising alternative to traditional antibiotics due to their membrane-disruptive action mediated by electrostatic interactions. This mechanism enables broad-spectrum activity while reducing the potential for resistance development.
Key Findings:
A comprehensive evaluation of recent literature reveals substantial progress across multiple cationic antimicrobial platforms. Enhanced surfactants with improved membrane-disrupting efficiency, advanced cationic polymer architectures with greater biocompatibility, and engineered antimicrobial peptides (AMPs) with tunable properties have been reported. Furthermore, quaternary ammonium-based polymeric systems and rapidly expanding ionic-liquid antimicrobials demonstrate significant potential for diverse therapeutic and material applications.
Conclusions:
Cationic antimicrobial agents are advancing through varied chemical designs and formulation strategies, offering effective tools against resistant bacterial strains. Continued innovation across surfactant, polymer, peptide, and ionic-liquid systems highlights their increasing promise for both clinical and industrial implementation.
