Fluorescence images of 200 μg pristine Survanta and ETS-exposed (TSP = 77 mg/m3) Survanta doped with 1% mol Texas Red-DHPE. Images are 171 μm × 171 μm and were acquired on the second cycle. The darker condensed phase forms a continuous network surrounding the lighter liquid expanded phase. (a) Survanta and (b) ETS-exposed Survanta a saline buffered subphase at Π = 20 mN/m during compression. (c) Survanta and (d) ETS-exposed Survanta at Π = 40 mN/m during compression. (e) Survanta and (f) ETS-exposed Survanta at the collapse plateau, Π = 67 mN/m, during compression. Arrows indicate cracks and folds in the monolayer due to collapse. (g) Survanta and (h) ETS-exposed Survanta at Π = 40 mN/m during expansion. (i) Survanta and (j) ETS-exposed Survanta at Π = 10 mN/m during expansion. ETS exposure has less effect on the morphology of the Survanta film than on Curosurf films.
