BIOSENSOR EQUIPPED WITH SAMPLE INTRODUCING PART WHICH ENABLES QUICK INTRODUCTION OF A SMALL AMOUNT OF SAMPLE

摘要

The present invention relates to an electrochemical-type biosensor with a sample introducing portion which can quickly and precisely introduce a blood sample without pre-treatment, wherein the sample introducing portion is added sample introducing passage and air passage formed cross, sample introducing passage and air passage It has a structure with a protrusion formed on a portion meeting point. Biosensors of the present invention includes a sample introducing portion of the structure is the working electrode, an auxiliary electrode or a reference electrode is to see to form a flat type biosensor, or the auxiliary electrode formed on a substrate such as on an upper substrate facing the working electrode made Face-to-face biosensor, or the planar face type and can be applied to both the differential expression biosensor implementation to process the signal to the differential expression. Biosensors of the invention can be introduced constantly without pretreatment very small clinical samples of less than 1 ㎕, has the advantage to end the measurement on the introduction of the sample within 5 seconds, and the reproducibility and reliability, excellent structure It has the advantage of being able to produce an extremely simple and inexpensive to mass.
