METHOD AND SYSTEM FOR DETERMINING THE CONCENTRATION OF AN ANALYTE/ENZYME COMPLEX OR OF AN ANALYTE/ENZYME CONJUGATE, ESPECIALLY FOR THE ELECTROCHEMICAL DETECTION OF THE ANALYTE |
摘要 |
A method follow the change in concentration of a redox-active substance, whereby suitable potentials for a reduction process or an oxidation process are applied to the working electrode of a measuring device. The potential of the working electrode is pulsed and measuring phases and relaxation phases are alternately produced, the pulse lengths of measuring phase and relaxation phase being determined in a suitable manner. A rapid relaxation of the concentration gradient is electrochemically forced so that the measurement can be carried out on simple transducer arrays. A device for carrying out the method includes a transducer array in addition to a suitable potentiostat. The transducer array can be formed of a planar metal substrate on which at least one flexible insulator is disposed, the metal surface and the insulator surface being firmly linked. The transducer array can also be formed of silicone-based CMOS structures. |
