Abstract (en)
[origin: WO2004059305A2] The invention relates to an electrical substrate for use as a carrier of biomolecules in a method for electrochemical detection in an electrolytic solution. Said substrate comprises an insulating carrier plate (12) with a conductive pattern (20; 20A-20C, 28) containing printed conductors (20; 20A-20C) and connection contact surfaces. The printed conductors (20; 20A-20C) are equipped with test sites (24) for the application of biomolecules (26), comprise a metal core (14) consisting of a highly conductive base metal and an external gold layer (18) and are provided with a diffusion barrier layer (16), which prevents direct contact between the electrolytic solution and the metal core (14) during the electrochemical detection method.
