The immobilization techniques presented represent an innovative method for the highly specific determination of antigens and other proteins in a very short time and may be a useful tool for the industrial preparation of highly sensitive biosensors. Non amphiphilic alkylated cellulose films are used as matrices to reduce non-specific interactions with biomolecules. These films are transferred onto waveguides by using the Langmuir-Blodgett- technique. After photochemical stabilization the cellulose films serve as excellent matrices for the immobilization of proteins at high density. Furthermore, one-step immobilization of a mixed photopolymer antibody film with a continuously operating LB-trough is demonstrated. The activity and specificity of immobilized antibodies and streptavidin is controlled by an enzyme-linked immunosorbent assay (ELISA) and an evanescent wave immunosensor.
