Solution evaporation drives the growth of fatty acid vesicles. Myristoleate (MA) vesicles, initially at 5 mM lipid concentration, were concentrated by gentle evaporation (Materials and Methods) and changes in surface area monitored by FRET at time points of 3, 10, and 24 h. Data are shown for two independent experiments (solid circles, squares) and are in agreement with that predicted from measured apparent micelle–vesicle partition coefficients (dashed line). An identical experiment with dimyristoleoyl phosphocholine (PC) vesicles did not show growth (points labeled x).
