    • The phase transitions of L-DPPC on water as detected by BAM and LSM, including static roughness formation and budding, were similar to those found on buffer, except that on water the arms of the flat domains were thinner and deformed more easily during compression, and the budding above π = 60 rnN/m covered nearly the entire monolayer. The isotherms on water and buffer were indistinguishable.

    • Irrespective of the angular-integrated scattered intensity, the upper and lower bubble extremities scatter light into cones that are not collected by the LSM objective (Arimoto, R.;. Murray, J. M. Biophys. J. 1996, 70, 2969).

    • The lack of scattering from edges nearly parallel to the plane of incidence indicates that both the gas bubble and the TC domain edges are smooth in-plane on the micron scale.

    • Compression-expansion cycles up to π = 40 mN/m showed minimal hysteresis, but in cycles extending above the shoulder at π ∼ 55 mN/m and below collapse at π = 71 mN/m, the expansion and recompression showed a shift to lower area, indicating loss of material onto the ribbon barrier (not shown). Furthermore, isotherms of L-DPPC monolayers on the leak-proof continuous interface of a captive bubble confirm the trough leakage. Under similar experimental conditions, the captive bubble isotherm from π = 0 to π = 71 mN/m is indistinguishable from that in the ribbon trough except there is no shoulder at π = 55 mN/m and no evidence of material loss (Crane, J. M.; Putz, G.; Hall, S. B. Biophys. J. 1999, 77, 3134).

    • note
    • Experiments show that nonlipid particles can originate from the air, water, buffer salts, and possibly organic solvents. These particles are usually undetectable in BAM. Control experiments with lipid monolayers other than L-DPPC which contained nonlipid particles but did not show static roughness formation or budding demonstrate that nonlipid particles do not cause these topographic transitions.
