FILTER CHIP AND METHOD FOR MANUFACTURING FILTER CHIP

摘要

A filter chip and a manufacture method thereof are provided to obtain maximum amount of blood plasma by increasing capillary force of a fluid inlet and to remove blood cells and minute particles, which obstruct diagnosis or analysis. A filter chip comprises: a filter(130); a lower plate structure(110) with a groove(111) formed therein in order to settle the filter; an upper plate structure(120) covering the upper area of the lower plate structure; a fluid inlet(140) formed in one region of the upper plate structure in order to inject fluids; and a fluid outlet(150) formed lower than the fluid inlet in order to flow the fluid out. The width of the filter and groove becomes narrow from the fluid inlet side to the fluid outlet side so as to induce rapid capillary force as the fluid passes through the filter.
