BIOSENSOR UND VERFAHREN ZU DESSEN HERSTELLUNG

摘要

A biosensor according to the present invention includes a reagent immobilization part (5) where an antibody for a measurement target in an inspection target solution is immobilized, and a marked reagent holding part (4) where an antibody which is marked at a part of a development layer in a dry state to be eluted by development of the inspection target solution is held, at parts of the development layer for developing the inspection target solution, and measures a bonding amount of the marked reagent bonded in the reagent immobilization part (5), thereby qualitatively and quantitatively measuring a measurement component in the inspection target solution. In such bionsensor, side faces of the development layer which are parallel to the direction of the inspection target solution permeating are partially or entirely melted and cured to be sealed. According to the so-constituted biosensor, the permeation of the inspection target solution in the development layer is arranged, and a low-cost and high-accuracy biosensor and a manufacturing method thereof can be realized by a simplified biosensor manufacturing method.
