A protein adsorbed shapable electroconductive polymer film comprising
1) a film made of a composition comprising
a) at least one polyheteroaromatic compound or aniline in oxidized, polycationic form, and
b) at least one polyanion of a film-forming thermoplastic polymer containing sulfated alcoholic groups and/or sulfonatalkylated groups in repeating structural units, wherein the group -(CnH2n)- is linear or branched C₂-C₁₂-alkylene containing 2 to 5 C-atoms in the carbon main chain, the alkylene being unsubstituted or substituted by C₁-C₄-alkoxy; and
2) a protein adsorbed on said film.
This protein adsorbed shapable electroconductive polymer film can be suitably applied as biosensors, bioreactor materials and immunosensors.
