Fig. 6.10. Time dependence of curvature fluctuations of a giant lipid vesicle with stress-sensitive alamethicin channels in its membrane. Inside the vesicle there is a ferricyanide solution undergoing a photochemical reaction under illumination, which produces a pH gradient and a photopotential across the membrane. The graph shows the second Legendre polynomial amplitude of the angular autocorrelation function of the vesicle radius as a function of time. Brief episodes (peaks) of extensive thermal fluctuations in a tension-free membrane are separated by long periods of a tensed, non-fluctuating vesicle membrane. (V. Vitkova, A.G. Petrov, unpublished.)...

Let be the stretching elasticity of the membrane, and let k, k, and Cq be the bending elasticity, the saddle splay bending elasticity, and the spontaneous curvature of the membrane [5,6]. Later on, attention is restricted to a quasispherical flaccid fluctuating vesicle. Only the case of fluctuations with magnitudes much less than the radius of the vesicle are considered. Let the area of the tension-free flat membrane of the vesicle be Sg, and its volume (assumed constant in time) be If Choose a laboratory frame of reference XYZ with origin O inside the vesicle. Let 0, q> be the...
