Our approaches to the developments of bilayer transduction devices are described. First approach is the combination of host-guest chemistry and synthetic bilayer membrane chemistry. Mixed bilayer membranes of chiral aromatic amphiphiples and crown ethers can descriminate ionic signals with high selectively throgh transduction to spectroscopic information (Spectrochemical transducer).<BR>Secondly, excitation phenomena of synthetic bilayers are described. Electric measurements were made for Millipore membranes impregnated with polyion complexes of bilayer membranes. Self-osillation of the membrane electric potential was observed at temperatures near phase transitions. Here, bilayers act as electrochemical transducer from d. c. informations to a. c. informations. Finally, a potential of molecular bilayer assemblies as a transducer of chemical information is further emphasized with a. c. impedance characteristics of bilayer-modified electrodes.
