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.

Method of depositing S-layer proteins on a carrier to immobilize functional molecules

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.
