A biosensor and a method for manufacturing the biosensor. The biosensor comprises an insulative substrate (1), an electrode system (2, 3, and 4), a reagent, and an insulating layer (5). The insulating layer (5) covers a part of the electrode system (2, 3, and 4). Also, a closed region (6) without the insulation layer is formed at where the reagent is. The closed region (6) is provided with an enclosing border having no sharp corner. The reagent covers the closed region (6) and does not go beyond the enclosing border. The biosensor also comprises an assisted diffusion electrode (12). The use of the enclosing border having no sharp corner and of the assisted diffusion electrode (12) reduces the edge effect of the reagent, allows the reagent to diffuse uniformly at response areas of the electrodes, effectively controls the amount of reagent used, reduces product costs, and allows for simple manufacturing. |

1. A biosensor, featured in comprising an insulative substrate and an electrode system on the insulative substrate, the electrode system comprising a reaction reagent that can react with samples to be detected and an insulating layer thereon; the insulating layer partially covering the electrode system and forming a closed region, at the location where the reaction reagent lies, without any insulating layer covered, the reaction reagent lying on a part of the electrode in the closed region; the closed region, formed by the insulating layer, comprising closed boundary without sharped corners; and the reaction reagent covering the closed region without extending beyond the closed boundary. |
