摘要：

Self-assembly solid supported bilayer lipid membranes(s-BLMs) modified with crown ethers were formed on metalic wire, The stability and the electrochemical characteristics of the s-BLMs depended on the variety of metalic wire, organic solvent, lipids and molecular structures of crown ethers. The membrane potentials of the s-BLMs prepared with stainless steel wire in mixed solution of squalane saturated cholesterol and crown ether in CHCl3 were determined. The cavity size and negative electricity of the ether ring of crown ether molecules are favorable to the selective complexation with metal cations (M(+), e.g, Li+, Na+, K+) in the aqueous solution, The change of [M(+)](10(-4)-10(-1) mol/L) would result in a Nernst corresponding in the membrane potential.
