Gramicidin conducting dimmers in lipid bilayers are stabilized by single-file ionic flux along them
Article Abstract:
Gramicidin D is incorporated in a biomimetic membrane consisting of a lipid bilayer tethered to a mercury electrode through a hydrophilic spacer and its behavior is examined in aqueous KCl by potential-step chronocoulometry and electrochemical impedance spectroscopy. The results have shown that gramicidin has a low tendency to form dimmers in the absence of ionic flux.

Tethered bilayer lipid membranes studied by simultaneous attenuated total reflectance infrared spectroscopy and electrochemical impedance spectroscopy
Article Abstract:
The influence of the lipid orientation of lipids on a gold film on the dichroic ratio is studied by simulations of spectra with a matrix method for anisotropic layers. The result shows that for certain tilt angles of the dielectric tensor of the adsorbed anisotropic layer dispersive and negative absorption bands are possible.

Pore-suspending lipid bilayers on porous alumina investigated by electrical impedance spectroscopy
Article Abstract:
A technique to modify the substrates with respect to their electrical properties, leading to a significantly increased capacitance of porous alumina, which allowed for a sensitive detection of pore spanning lipid bilayers by impedance spectroscopy is established.
