Figure 7. Thermophoretic properties can be designed by working with vesicles of mixed lipid composition.

Here the Soret coefficients for vesicles of the ternary mixtures SQDG/DOPG/chol (27.5:27.5:45 mol%) and DOPC/DOPG/chol (27.5:27.5:45 mol%) are seen to transition between the limiting values for each lipid component (dashed lines), as the mean temperature is increased. At low temperatures, the Soret coefficients closely match the PG-type lipid. Error bars on data indicate the s.d. of S_T from five measurements taken at 5 min time intervals after achieving steady state.
