The excellent and unique features of cell membranes, such as antifouling, self-healing, controllable permeability, may have great implications in exploitation of artificial membranes.

A membrane that hasselective permeabilityallows only substances meeting certain criteria to pass through it unaided. In the case of the cell membrane, only relatively small, nonpolar materials can move through the lipid bilayer (remember, the lipid tails of the membrane are nonpolar). Some examples...

This makes the lipid bilayer less deformable and decreases its permeability to small water-soluble molecules. Without cholesterol (such as in a bacterium) a cell would need a cell wall. Cholest 13、erol prevents crystallization of hydrocarbons and phase shifts in the membrane. Cholesterol Figure. ...
Cell Membrane Structure and Function1 Membranes and Cell TransportAll cells are surrounded by a plasma membrane. Cell membranes are composed of a lipid bilayer with globular proteins embedded in the bilayer.On the external surface, carbohydrate groups join with lipids to form glycolipids, and with ...
[34,39]. For example, cytotoxic ROS react with polyunsaturated fatty acids to cause lipid oxidation and degradation, which affect the fluidity and permeability of cell membranes and hinder cell metabolism and ion-channel exchange [40]. In addition, iNOS was highly expressed in lesions after SCI ...

Although each of these membranes may subserve different functions, they all share two common properties: they exhibit both a selective permeability to lipid solvents as well as a high electrical resistance. These two properties suggest the presence of an underlying unit consisting of a lipid bilayer...
Electroporationis a biophysical phenomenon in which cellmembrane permeabilityis increased through the application of externalpulsedelectricfields (PEF).Reversibleelectroporation (RE) occurs when the cell membrane permeabilization is temporary and the treated cells survive. PEFs that lead to cell death are kn...
They surround certain cells (such as muscle cells), underlie epithelial cell sheets, and are interposed between two cell sheets (as in the kidney glomerulus). Note that in the kidney glomerulus both cell sheets have gaps in them, so that the basal lamina serves as the permeability barrier ...
