Abstract
A liquid mixture is assayed for a biologically active component that undergoes a reduction or oxidation reaction within a specific voltage range by immobilizing at an electrically conductive surface, a binding partner for the component, exposing the surface to the component to permit complexing to occur, applying a voltage to the surface in a range which will cause the component to undergo an oxidation or reduction reaction, and measuring the resulting current as an indication of the presence of the component.
