IMMUNOSENSORY TRANSDUCER

摘要

Ref. 4090/2 16 The immunosensory transducer for surface plasmoresonance has a gold carrier, a two-dimensional matrix in the form of a monomolecular organic intermediate layer on this surface and a ligand or antiligand layer immobilized on this. The transducer in accordance with the invention is considerably simpler to produce than known transducers having a three-dimensional matrix. For the production, a monomolecular layer of alkyl derivatives with sulphur-containing groups is applied to the gold surface by spontaneous chemisorption and subsequently a ligand or antiligand suitable for the desired immune detection is immobilized on this layer.
