Osmotic Shrinkage of Giant Egg-Lecithin Vesicles [PDF]
Biophysical Journal, 1980 Osmotic shrinkage of giant egg-lecithin vesicles was observed by phase-contrast microscopy. The vesicles remained or became spherical when shrinking. Small and thick-walled vesicles formed visible fingers attached to the sphere. The water permeability of the single bilayer was found to be 41 micrometers/s.

Self‐Assembled Lipids as Soft Dielectrics
Advanced Functional Materials, EarlyView.Self‐assembled lipid bilayers serve as soft dielectric materials for ultrathin electronics. Using liquid‐metal parallel‐plate junctions, the capacitance and dielectric breakdown of dehydrated lipid films are characterized. Dielectric behavior is controlled by lipid molecular structure, cholesterol content, and assembly conditions, providing molecular ...

Programmed magnetic manipulation of vesicles into spatially coded prototissue architectures arrays
Nature Communications, 2020 To execute higher-order functions, cells self-assemble into spatially coded tissue configurations. Here the authors magnetically assembly giant unilamellar vesicles into three dimensional tissue-mimic structures with collective osmotic stability.
