File Name : figures2.pdf Caption : figure s2. a) schematic illustration of standard dls measurement (left) and spatially resolved-dls (right) b) representation of particle motion during laminar pipe flow of a nanosuspension. superimposed on the normal brownian motion of nanoparticles is the poiseuille laminar flow profile, both of which are spatially characterized using sr-dls. the broadband illumination from the nfs probe and backscattering are also indicated. c) autocorrelation functions measured simultaneously over a range of sample depths using sr-dls, the white arrow indicates the increase in local velocity for larger depths. image adapted from our previous publication 1. File Name : figures3.pdf Caption : figure s3. schematic view of the static mixer for proper mixing of the concentrated lipids and pure ethanol. File Name : figures4.pdf Caption : figure s4. the concentration of liposomes decreases over time in the presence of 50% v/v ethanol/pbs. liposomes were formed with 70 mm lipid in ethanol and tfr 62 ml /min-1 and the sample was diluted 10,000 times with a mixture of pbs and ethanol (1:1 ratio). data were obtained from nta device.
