Abstract
A sintered powder electrode has a biochemically active layer embedded in pores of the electrode. Molecules bind to or are displaced from the biochemically active layer, which drastically changes electrical properties of the electrode. The electrode can be used in an affinity chromotography column or in a capacitive affinity sensor.
