Interaction of the cationic peptide bactenecin with mixed phospholipid monolayers at the air-water interface

► Interaction of bactenecin with phospholipids mixture at the air-water interface. ► Effect of NaCl in the subphase on the peptide adsorption at the DPPC:DMPG monolayer. ► Evidence of peptide-phospholipids aggregation to build a carpet-like structure. ► Critical peptide concentration to build holes as predicted by the carpet model.
