A novel flow injection amperometric urea biosensor, based on the incorporation of urease into a conductive polypyrrole film, has been developed. The amperometric detection .of as little as 3 ppm of urea by flow injection analysis (FIA) was accomplished in 0.05 M phosphate buffer (pH 7.0) with the ap
## Abstlnet An amperometric biosensor for fructose was fabricated by co-immobilizing a pyrrolo quinoline quinone (PQQ) enzyme (fructose dehydrogenase, FDH) with mediator in a thin polypyrrole (PP) membrane. Electron transfer between the prosthetic PQQ of FDH and the transducer electrode was promot
