(A) Cartoon of expanded Survanta film at low surface pressure, Π, composed of a relatively high density of unsaturated lipids at the air-water interface; (B) compressed Survanta film at medium Π showing desorption of primarily unsaturated lipids, leaving a monolayer enriched in saturated lipids; (C) collapsed Survanta film at high Π with collapse structures pushed into the interfacial region, but no multilayers; (D) BAM image of highly reflective collapse structures seen as bright cracks.
