Notes:
Two-diminsional crystalline surface layers (S-layers) composed of prtein or glucoprotein subunits are one of the most commonly observed prokaryotic cell envelope structures. lsolated S-layer Subunits are endowed with the ability to assemble into monomolecular arrays in suspension, on surfaces or interface by an entropy-driven process. S-layer lattices are isoporous structures with functional groups located on the surface in an identical position and orientation. These characteristic featupes have alreadu led to applicatioinns of S-layers as (1) ultrafilration membranes with well-defiled mmlecular weight cut -ooffs and excellent antifouling characteristics, (2) immobilization matrices for functional molecules as required for affiviy and enzyme memberanes, affiniy micricarriers and biosensors, (3) conjugate vaaines, (4) carriers for Langmuir-Blodgett films and reconstituted biological memberanes, and (5) patterning elements in molecular nanotechnology.
