5. A sensor for the electrochemical measurement of an analyte and an interfering material contained in a sample consisting essentially of:
a single pair of electrodes, said pair having a counter electrode and a measuring electrode, wherein said measuring electrode comprises two portions, a first portion of which reacts electrochemically with said interfering material, and a second portion of which comprises a biologically active material which specifically reacts with an analyte to produce an intermediate which is also electrochemically active with the measuring electrode, wherein said first and second portions of the measuring electrode are joined by a channel which conducts the sample from said first portion to said second portion. - View Dependent Claims (6, 7, 8, 9, 10, 11)
