[Determination of the permeability coefficients of spherical bilayer membranes for ions and nonelectrolytes].

A method for determining permeability of spherical lipid bilayer membranes for ions and nonelectrolytes is proposed. This method is based on measuring the quantity of substances penetrating inside some membrane limited volume. This method allows to measure the permeability coefficient of several substances in one membrane. Permeability coefficients have been measured in non-modified membranes for glucose. Li, K, and in membranes modified with amphotericin B for glucose, ribose and lactate.
