ABSTRACT:
Provided is a disposable multi-layered filtration device for the separation of blood plasma which can be applied to a biochip and appropriate for disposal uses. The filtration device for the separation of blood plasma includes: an upper substrate including a blood inlet; an intermediate substrate including a filtering unit for extracting blood plasma from blood flowing through the blood inlet; and a lower substrate including an air outlet, wherein the upper substrate, the intermediate substrate, and the lower substrate are stacked and adhered.
