For the practical use as a biosensor, a rubber electrode bound by polybutadiene was newly devisedfor the determination of hydrogen peroxide. Then its electrochemical behaviors were investigated. The signal.(vs. Ag/AgCl) with a detection limit of1.4×104 M and its potential dependence was linear in the experimental range. Especially its Lineweaver-Burkplot showed a very good linearity giving the evidence of a good enzyme immobilization on the surface ofthe electrode. And mechanical stability of the electrode resulted from using rubber binder presented a newpossibility for the practical use of biosensor.
