Abstract

The possible formation of statistical pores through black lipid membranes may constitute a new mechanism for the explanation of transversal diffusion of lipid molecules through bilayers. In this work, we calculate the flip-flop diffusion coeficient, which is related to the mean number of statistical pores formed on the planar bilayer and the lateral diffusion coeficient. Its approximately calculated value is: Dff = 10−3 m2 s−1.

    Preliminary evidence suggests several possible mechanisms for the loss of membrane phospholipid asymmetry after ultrashort pulsed electric field exposure. Depending on cell size and pulse parameters, nanoelectropulse-induced PS translocation could result entirely from intracellular effects such as calcium bursts (Vernier et al., 2003b), or from nonporative dipole interactions with membrane components (Miller, 2002), or as a consequence of diffusion facilitated by formation of nanosecond-duration, nanometer-diameter membrane openings of the external membrane (Taupin et al., 1975; Popescu and Victor, 1991), or some combination of these. To evaluate these and other hypotheses it is essential to know the electrophysical boundaries of the pulsed field exposures that produce membrane phospholipid translocation.

    Translocation events from one monolayer to another (e.g. flip-flop transitions) are very improbable processes (see the section 8 of this chapter). The flip-flop diffusion coefficient (Dff) is in the order of 10−23 m2s−1, which is much smaller than Dl [45]; in each monolayer there is a short range order, which is characteristic to the liquids.
