co-immobilization of enzyme with redox polymer poly(vinylpyridine) complex functionalized with osmium bis(bipyridine) chloride on an electrode. The enzyme electrode readily oxidizes primary alcohols and secondary alcohols with maximum current densities varying between 0.43 and 0.98 A per m2 depending on the substrate and the operation temperature. The enzyme electrode is enantioselective in the oxidation of secondary alcohols. A strong preference is observed for the (S)-2-alcohols, the enantioselectivity increases with increasing chain length. The enantiomeric ratio E increases from 13 for (R,S)-2-butanol to approximately 80 for (R,S)-2-heptanol and (R,S)-2-octanol
