Abstract
Porous polymer electrode assemblies are useful in the detection or quantification of a variety of analytes. By preparing a porous monolith, and applying a conductive polymer to the monolith, a porous matrix is prepared that combines favorable conductive properties, by virtue of the presence of the conductive polymer, with the porous character of the underlying monolith. The resulting porous electrode can be used for qualitative or quantitative analysis, and the capture and/or release of selected charged materials, such as nucleic acids. The pores of the electrode matrix may also be filled with nonconductive material, yielding electrodes having a plurality of discrete conductive surfaces.
