Studies of electric capacitance of membranes. I. A model membrane composed of a filter paper and a lipid analogue.

摘要: A hydrophobic filter paper of a given pore size containing synthetic lipid, i.e. dioleyl phosphate, was interposed between aqueous electrolyte solutions having the same chemical composition and temperature. The electric capacitance conductance membrane immersed in various concentrations KCl were measured frequency range from 20 to 3 x 10(6) cycle/sec. observed found be strongly dependent on applied frequency. theory is proposed account for this dispersion impedance present membrane-electrolyte system. attributed formation bilayer membranes lipid inside paper. effects salt concentration, adsorbed quantity are discussed terms distribution function bilayers formed within
