Tension-Induced Morphological Transition in Mixed Lipid Bilayers
  Recently, Rozovsky et al. reported on the morphology and dynamics of superstructures in three-component lipid bilayers containing saturated and unsaturated lipids as well as cholesterol [J. Am. Chem. Soc. 127, 36 (2005)]. We comment that the observed sequence of the stripe to hexagonal morphological transition in mixed bilayers can be attributed to an enhanced membrane surface tension that is induced by the vesicle adhesion on the solid surface.
