Abstract
(EN)
The present invention provides a biosensor electrode manufacturing method and a biosensor electrode. The biosensor electrode manufacturing method comprises the steps of: a) preparing an electrode base having nanostructures formed on the surface thereof so as to constitute a pattern, each nanostructure comprising a column portion formed to stand upright and a protrusion portion formed on the outer periphery of the column portion so as to protrude in a radial shape; b) oxidizing the surface of the prepared electrode base by plasma; and c) forming a plating film on the electrode base. The biosensor electrode manufacturing method comprises a step of stretching the cured electrode base so as to form cracks on the surface of the electrode base and on the nanostructures. Accordingly, the nanostructures comprise multiple column portions formed on the surface of the electrode base so as to stand upright and protrusion portions formed to protrude from the outer peripheries of the column portions in radial shapes, respectively, such that a pattern is formed on the surface of the electrode. Cracks are formed by stretching applied in the horizontal direction. As a result, the biosensor electrode has a larger surface area in which sensing factors are attached than a conventional planar electrode, thereby substantially improving the sensitivity thereof compared with that of the conventional planar electrode.

La présente invention concerne un procédé de fabrication d'électrode de bio-capteur et une électrode de bio-capteur. Le procédé de fabrication d'électrode de bio-capteur comprend les étapes consistant à : a) préparer une base d'électrode ayant des nanostructures formées sur sa surface de façon à constituer un motif, chaque nanostructure comprenant une partie colonne formée de façon à se tenir debout et une partie saillante formée sur la périphérie extérieure de la partie colonne de manière à faire saillie sous une forme radiale; b) oxyder la surface de la base d'électrode préparée par plasma; et c) former un film de placage sur la base d'électrode. Le procédé de fabrication d'électrode de bio-capteur comprend une étape consistant à étirer la base d'électrode durcie de façon à former des fissures sur la surface de la base d'électrode et sur les nanostructures. Par conséquent, les nanostructures comprennent de multiples parties de colonne formées sur la surface de la base d'électrode de manière à se tenir debout et des parties saillantes formées de façon à faire saillie à partir des périphéries extérieures des parties de colonne dans des formes radiales, respectivement, de telle sorte qu'un motif est formé sur la surface de l'électrode. Des fissures sont formées par étirement appliqué dans la direction horizontale. Par conséquent, l'électrode de bio-capteur présente une surface plus grande dans laquelle des facteurs de détection sont fixés à une électrode plane classique, ce qui permet d'améliorer sensiblement la sensibilité de celle-ci par rapport à celle de l'électrode plane classique.
