Abstract
Electrochemical biosensor test strip, fabrication method thereof and electrochemical biosensor are disclosed. The electrochemical biosensor test strip is fabricated by cutting a groove in a first insulation base in the breadth direction, forming two electrodes parallel to length direction on the first insulation base by sputtering using shadow mask, fixing a reaction material comprising an enzyme which reacts an analyte and generates current corresponding to the concentration of analyte across the two electrodes on the groove of the insulation base, and affixing a cover to the first insulation base. The groove of the first insulation base and the cover make a capillary at the position where the reaction material is fixed. The fabrication method can lower the cost for fabricating the test strip by forming thin electrodes.
