File Name : hp_nse_fig_s1.eps Caption : fits of the intermediate scattering functions to eq. 1 (dashed line) and to eq. 5 (solid line). File Name : hp_nse_fig_s2.eps Caption : amplitude a(q) obtained from fitting data to eq. 5 with γzg as a shared parameter. File Name : figure s3 top.tif Caption : determination of vesicle rh using dls. (top) rh of dophpc:dophpe (9:1) vesicles as a function of mol% squalane. data from two sets of samples are shown in open squares (set 1) and closed squares (set 2). the two sets differ mostly in the time frame the dls measures were taken. set1 was measured after hp treatment. set 2 was measured directly following extrusion. each sample was measured three times and the average value reported. error bars indicate the standard deviation in vesicle size, not the standard deviation of the triplicate measurements. dashed line indicates a linear fit of the values from both data sets. File Name : figure s3 bottom.tif Caption : (bottom) size distribution of vesicle rh for samples from two sets of measurements. the dashed lines indicate the data from set 1 and the solid lines indicate the data from set 2. measurements were made of dophpc:dophpe (9:1) containing 0 mol% (red), 1 mol% (yellow), 2.5 mol% (green) and 5 mol% (blue) squalane.
