Vibrational sum frequency generation (VSFG) and Langmuir trough surface pressure measurements were used to investigate how the soluble surfactant perfluorooctanoic acid (PFOA) affects dipalmitoylphosphatidylcholine (DPPC) monolayers adsorbed to the air–water interface. Studies were performed as a fu...
