Artificial lipid mono- and bilayers have been used extensively to study the basic principles of self-organized molecular layers especially in the context as models of biological membranes. In particular, the incorporation of proteins in a functionally active state in lipid bilayers, has enabled the elucidation ofstructure-function relationships of many biologically important membrane proteins under defined conditions. 1-4

There is a new, fast growing interest in the realization of long-lasting, stable lipid layers on solid supports, for application in molecular (bio) electronics and (bio) sensors, as well as for fundamentalstructural studies using scanning probe techniques. 6-11 One of the most attractive goals would be the incorporation of intrinsic membrane proteins into such supported lipid layers, either for the development of highly selective sensor devices based on natural signal recognition and amplification principles or for …
