title: Amperometric enzyme-immunosensor based on ferrocene-mediated amplification.
abstract: Coimmobilized glucose oxidase and anti-T4 antiserum are employed in the construction of a biosensor for thyroxine measurements. The resulting enzyme-immunosensor yields an amplified response to T4 with a detection limit of 15 nM.
