title: Fluorescence microscopy to study pressure between lipids in giant unilamellar vesicles.
abstract: The authors developed a technique to apply high hydrostatic pressure to giant unilamellar vesicles and to directly observe the consequent structural changes with two-photon fluorescence microscopy imaging using high numerical aperture oil-immersion objectives. The data demonstrate that high pressure has a dramatic effect on the shape of the vesicles, and both fluidity and homogeneity of the membrane.
