Abstract

Provided is a non-coding type biosensor. The non-coding type biosensor includes a first electrode including a first sub-electrode and a plurality of second sub-electrodes that are spaced apart from the first sub-electrode, ends of at least some of the plurality of second sub-electrodes being connected to the first sub-electrode, a reaction chamber in which a target material and a mixture solution react with each other, the reaction chamber contacting opposite ends of the plurality of second sub-electrodes, and a second electrode of which one end contacts the reaction chamber.

Claims

1. A non-coding type biosensor comprising:

a first electrode comprising a first sub-electrode and a plurality of second sub-electrodes that are spaced apart from the first sub-electrode, ends of at least some of the plurality of second sub-electrodes being connected to the first sub-electrode;

a reaction chamber in which a target material and a mixture solution react with each other, the reaction chamber contacting opposite ends of the plurality of second sub-electrodes; and

a second electrode of which one end contacts the reaction chamber,

wherein in the first electrode, at least some of the plurality of second sub-electrodes are not electrically connected to the first sub-electrode.

2. The non-coding type biosensor of claim 1, wherein in the first electrode, the ends of at least some of the plurality of second sub-electrodes are connected to the first sub-electrode through electrode fabricating areas, respectively.

3. The non-coding type biosensor of claim 2, wherein shapes of the electrode fabricating areas are different from shapes of the second sub-electrodes connected to the first sub-electrode.

4. The non-coding type biosensor of claim 1, wherein the number of the second electrodes, which are not electrically connected to the first sub-electrode, of the plurality of second sub-electrodes varies according to a mixture solution in the reaction chamber.

5. The non-coding type biosensor of claim 1, wherein the plurality of second sub-electrodes have the same area.

6. The non-coding type biosensor of claim 1, wherein the at least some of the plurality of second sub-electrodes have different areas.

7. A non-coding type biosensor comprising:

a first electrode comprising a first sub-electrode and a plurality of second sub-electrodes, the first sub-electrode comprising a body part and a working part; and

a reaction chamber in which a mixture solution that reacts with a target material is located, the reaction chamber contacting the working part and the plurality of second sub-electrodes respectively,

wherein ends of at least some of the plurality of second sub-electrodes are respectively connected to the body part.

8. The non-coding type biosensor of claim 7, wherein

the ends of at least some of the plurality of second sub-electrodes are respectively connected to the body part through electrode fabricating parts, and

shapes of the electrode fabricating parts are different from shapes of the second sub-electrodes connected to the body part.

9. The non-coding type biosensor of claim 7, wherein an area of the first sub-electrode is larger than areas of the plurality of second sub-electrodes.

10. The non-coding type biosensor of claim 9, wherein the at least some of the plurality of second sub-electrodes have different areas.

11. The non-coding type biosensor of claim 7, further comprising:

a second electrode that contacts the reaction chamber while being spaced apart from the first electrode,

wherein the first electrode is a working electrode and the second electrode is a reference electrode.
