[On measurements of higher harmonics of transmembrane current]
Abstract:
Measurements of higher harmonics of transmembrane current in bilayer lipid membranes from diphytanoyl phosphatidylcholine (DPhPC) in n-decane and n-tetradecane, caused by alternating voltage applied to the membrane, have been conducted. A universal relation between the amplitudes of harmonics was suggested and experimentally checked. This allowed one to calculate the coefficients of expansion of membrane capacity in series with even powers of membrane voltage and to compare the inhomogeneity of membranes from diphytanoyl phosphatidylcholine in n-decane and n-tetradecane with respect to thickness.
