Problems solved by technology

The screen printing method is a printing method using platinum ink, carbon ink, or silver / silver chloride ink, which requires low equipment costs, but there is a problem that it is difficult to adjust the resistance change to manufacture sensor electrodes that require reproducibility
However, since the screen printing method using carbon ink results in low hardness and uneven thickness, it has many defects such as irregularity in resistance, generation of carbon particles, and complicated process

Abstract

The present invention relates to an electrochemical biosensor electrode strip fabricated by forming a carbon layer on a non-conductive substrate made of polymer material, forming a metal layer containing titanium thereon, and performing patterning.

Description

technical field [0001] The invention relates to an electrochemical biosensor electrode belt which can be manufactured at low cost and has excellent performance and a manufacturing method thereof. More particularly, the present invention relates to an electrode strip for an electrochemical biosensor test strip for quantitative analysis of a specific substance in a biological sample, such as glucose in blood, and a manufacturing method thereof. Background technique [0002] In the field of medicine, electrochemical biosensors have recently been frequently used to analyze biological samples including blood. In particular, electrochemical biosensors using enzymes are widely used because they are easy to apply, have high measurement sensitivity, and can quickly obtain results. [0003] As an example of such an electrochemical biosensor, there is a glucose measuring biosensor. Its working mechanism will be described below. [0004] For the glucose measuring biosensor, a certain...
