Abstract
An ultramicroelectrode assembly which generally comprises an electrically nonconducting host membrane having a plurality of micro-sized pores extending through the membrane, and a macro-sized substrate electrode in contact with this host membrane. The host membrane has its pores impregnated with an electrically conductive medium, and the substrate electrode is in electrical contact with the impregnated pores of the host membrane. The electrically conductive medium is a carbon paste, and the substrate electrode includes a confined volume of such carbon paste in contact with an interior surface of the impregnated membrane.
