Linear amphipathic antimicrobial peptides kill bacteria through detergent-like membrane disruption rather than forming specific pores, with activity determined by the same physicochemical principles that govern detergent function.

What the researchers found
Linear amphipathic cationic antimicrobial peptides disrupt bacterial membranes through a detergent-like mechanism (carpet model) rather than specific pore formation, with antimicrobial potency governed by the same hydrophobic-charge balance as detergent activity.
