Patent ID: 8012322

Claim:
A biosensor for disease diagnosis using an electrode, comprising: a bottom plate including, a first base film having a first lead mounted at one side of the top surface thereof, a first electrode member formed on the first base film, one side of the first electrode member being the first lead, a first spacer formed on the top surface of the first electrode member so as to secure a first recess having a predetermined width formed on the first electrode member, and a first enzyme reaction layer formed transversely on the top surface of the first electrode member in such a fashion as to be positioned in the first recess of the first spacer; and a top plate formed integrally with the bottom plate and including, a second base film having a second lead mounted at one side of the top surface thereof, a second electrode member formed on the second base film, a second spacer formed on the top surface of the second electrode member so as to secure a second recess having a predetermined width formed on the second electrode member, and a second enzyme reaction layer formed transversely on the top surface of the second electrode member in such a fashion as to be positioned in the second recess of the second spacer, wherein the first and second base films are made of any one selected from heat-resistant polymers like polyethylene terephthalate (PET), polyethylene (PE) and polyvinyl chloride (PVC), the first spacer and the second spacer contact each other, and the first recess is formed transversely across the first base film from one lateral side of the first base film to an opposite lateral side of the first base film, and the second recess is formed transversely across the second base film from one lateral side of the second base film to an opposite lateral side of the second base film.
