Production of Isolated Giant Unilamellar Vesicles under High Salt Concentrations
The cell membrane forms a dynamic and complex barrier between the living cell and its environment. However, its in vivo studies are difficult because it consists of a high variety of lipids and proteins and is continuously reorganized by the cell. Therefore, membrane model systems with precisely controlled composition are used to investigate fundamental interactions of membrane components under...
متن کاملTension-induced pore formation and leakage in adhering vesicles
– The influence of inclusion-induced tension on pore formation is studied theoretically and experimentally. It is shown that fluorescently labeled lipids can enhance pore formation and induce leakage of adhering vesicles. These effects are more pronounced for smaller vesicles. The theoretical predictions are confirmed by experimental two-color fluorescent data. Finally, the influence of the por...
متن کاملOptically controlled pore formation in self-sealing giant porphyrin vesicles.
Efforts to develop self-contained microreactors and artificial cells have been limited by difficulty in generating membranes that can be robustly and repeatedly manipulated to load and release cargo from phospholipid compartments. Here we describe a purely optical method to form pores in a membrane generated from porphyrin-phospholipid conjugates electro-assembled into microscale giant porphyri...
متن کاملTrapping and release of giant unilamellar vesicles in microfluidic wells.
We describe the trapping and release of giant unilamellar vesicles (GUVs) in a thin and wide microfluidic channel, as they cross indentations etched in the channel ceiling. This trapping results from the reduction of the membrane elastic energy, which is stored in the GUV as it squeezes to enter into the thin channel. We demonstrate that GUVs whose diameter is slightly larger than the channel h...
متن کاملThermodynamic relaxation drives expulsion in giant unilamellar vesicles.
We investigated the thermodynamic relaxation of giant unilamellar vesicles (GUVs) which contained small vesicles within their interior. Quenching these vesicles from their fluid phase (T > T(m)) through the phase transition in the gel state (T < T(m)) drives the inner vesicles to be expelled from the larger mother vesicle via the accompanying decrease in the vesicle area by approximately 25% wh...
