The emergent disaster of antimicrobial resistance developed by virulent bacteria has highlighted the need to investigate substitutes for the presently existing antibiotics. Antibacterial peptides (ABPs) have arisen as promising substitutes because of their unique killing effect on bacteria: bacterial resistance toward ABPs is negligible. ABPs have many beneficial subsidiary effects, such as protection of labile bioactive compounds, and they can be covalently connected to different materials to enhance their antibacterial effect. Many researchers have investigated many applications of these peptides recently, such as in a variety of pharmaceutical dosage forms and wastewater treatment.
