Popis: | Biological cells are contained by a fluid lipid bilayer (plasma membrane, PM) that allows for large deformations, often exceeding 50% of the apparent initial PM area. Isolated lipids self‐organize into membranes, but are prone to rupture at small ( During their lifecycle, cells undergo remarkable deformations. The protective membrane holding together the cell (plasma membrane) must allow for such deformations. Here, plasma membrane extracts that retain some of the cellular deformability are studied. The underlying physics of the elastic response is identified and a synthetic biomaterial one magnitude softer and threefold more deformable than conventional synthetic cells is engineered. |
