[Diffusion of a fluorescent probe in egg lecithin multilayers and the effect of a permanent magnetic field].
A method is developed for determining the value of transverse diffusion coefficient through lipid multilayers. Using the absorption kinetics parameters of 1-aniline-8-sulphonate naphthalene (ANS) the value of diffusion coefficient was estimated as Dt = (3 +/- 1). X 10(-12) cm2 s-1 at (22 +/- 0.5) degrees C. The value of Dt was shown to increase under the action of the magnetic field parallel to the multilayer surface; a relative increase of Dt at field 1.3 T is +(40 +/- 15)%.
