title: [Conductivity fluctuation of lipid bilayer membranes formed on a substrate].
abstract: In the range of voltages -0.9-(+)0.9 V the fluctuations of conductivity of bilayer lipid membranes formed on the support (s-BLM) were measured. The new cut of the wire from stainless steel SS-10T served as the support. The similarity of current fluctuations for s-BLM as well as for support-electrolyte interface was observed, some quantitative distinctions are revealed. Three types of fluctuations are observed; 1) large current jumps observed as current steps at DC channel; 2) small current fluctuations near zero line with the spectrum of 1/f alpha type (flicker noise); 3) short current jumps, whose amplitudes are many folds higher than mean noise level, and the density of distribution function falls off as fluctuation magnitude raised to power 2.5 for s-BLM.
