Metal silicides as a novel electrode material in electrochemical sensors

We have studied the suitability of titanium silicide as an electrode material in electrochemical cells. The high chemical stability, low resistivity and possibility to immobilise biomolecules in combination with the possibility to manufacture structured electrodes with methods from the microelectronics industry make silicides interesting. As an example results from measurements with the enzyme horseradish peroxidase are given and compared with similar measurements with graphite and carbon paste electrodes.
