The outer membrane protein OmpF from Escherichia coli is a member of a large family of β-barrel membrane proteins. Some, like OmpF, are pore-forming proteins whilse others are active transporters or enzymes. We have previously shown that the recepto

Gating of an artificial receptor was monitored for the first time by impedance spectroscopy in tethered lipid bilayer. Subnanomolar concns. of antibody were detected by modulation of the channel activity. The principle of gating by an antibody is par

Structural changes of the Langmuir-Blodgett (LB) films of azobenzene accompanied by photoisomerization are described. First, photoisomerization is explained in terms of 'free volume'. In the polyion complex monolayers of amphiphiles having two azoben

By changing the surface pressure a drastic change of morphology was induced in monolayers of a surface-active squarylium dye and arachidic acid at the air-water interface. After transfer on solid supports, the films were investigated by atomic force

A Ca2+ sensor based on the admittance change of synthetic membranes supported on derivatized silicon electrodes is reported. The ion-sensitive membranes consist of mixed monolayers of phospholipid and the Ca2+-ligand ETH 1001. The electrodes are char
