Abstract: On a carrier surface, a layer of S-layer proteins is produced as a carrier of functional molecules. A solution containing S-layer proteins in the form of monomers or oligomers is brought into contact with the carrier surface. Electrochemical conditions are produced in the solution such that the S-layer proteins (SU) have an electrical net charge by establishing an electrochemical potential difference between the solution and the carrier surface such that the S-layer proteins accumulate on the carrier surface. A two-dimensional crystalline structure is formed in the layer, and this can occur at a time separate from the deposition of the S-layer proteins, and under different electrochemical conditions.

Abstract: A compound body can be constructed, using secondary cell wall polymers of prokaryotic microorganisms as bonding agent to anchor a monomolecular lattice to a support, with or without functional groups attached to the lattice. The lattice may be comprised of lipid or crystalline cell surface layer proteins. The support is illustrated by a micro-filtration membrane, a cell surface ultra-filtration membrane (SUM), and a micelle, respectively.

Abstract: On a carrier surface (CP), a layer of cell surface layer proteins (S-layer proteins) (SU, SM, SL) is produced as a carrier of functional molecules by virtue of a solution containing S-layer proteins in the form of monomers (SU) or oligomers (SM) being brought into contact with the carrier surface. To deposit the S-layer proteins, electrochemical conditions are set in the solution at which the S-layer proteins (SU) have an electrical net charge, and by setting the electrical potential of the carrier surface (CP) an electrochemical potential difference is produced between the solution and the carrier surface under whose effect the S-layer proteins from the solution accumulate on the carrier surface. In the layer formed in this way, a two-dimensional crystalline structure (SL) is then configured, wherein this can occur at a time separate from the deposition of the S-layer proteins and under different electrochemical conditions of the solution and/or the substrate.

Abstract: Use of secondary cell wall polymer for the directed monomolecular bonding of molecules, preferably molecular layers and/or attachment of molecules to molecules of a support, as well as a compound body completed according to this application.

Abstract: The invention relates to a method for producing a structured layer of defined functional molecules on the surface of a flat substrate, on the surface of which structures having different surface properties, at least as regards their hydrophobicity, are produced. A monolayer of a protein-containing crystalline cell surface layer (S layer) is deposited by recrystallization on said structured surface. Said S Layer binds only to those structured areas of the surface characterized by raised hydrophobicity. Alternatively, a structured S-layer may also be produced on the basis of a monolayer of an S layer deposited on a substrate by irradiating predefined sections of said layer to be structured with radiation of a predetermined intensity and energy. In the irradiated sections of the S-layer this suppresses the binding or intercalating ability of at least one surface.

Abstract: Superior pharmaceutical compositions which comprise carriers coupled to epitope-bearing moieties are described. The carriers are crystalline or paracrystalline glycoproteins, especially those derived from S-layers of microbial cell walls. These conjugates are capable of eliciting the formation of antibodies as well as a T-cell response.
