[Piezoeffect, baseline conductivity and filtration coefficients of lipid bilayer membrane].
A piezoeffect in bilayer lipid membranes (BLM), i.e. a generation of alternate electrical current y through a membrane under alternate pressure gradient in the absence of constant transmembrane potential is investigated. It is shown that y is not connected with the membrane deformations, it is generated with electroosmotic flow of K+ ions, its amplitude increases with a rise of BLM phonic conductance and is probably connected with defects in BLM structure. The value of the filtration coefficient Lp is estimated.
