Membrane structure body having matrix structure and biomolecule filter using same

Abstract

A membrane structure body having a matrix structure and a biomolecule filter using the same are disclosed. The membrane structure body having a matrix structure, according to one embodiment of the present invention, comprises: a filtering part which includes a window region in which a plurality of window cells are formed in a matrix shape and a blocking region in which the window cells are not formed, and which filters biomolecules from a sample moving along the window region; and a support part extending from the filtering part so as to support the filtering part, wherein each window cell formed in the window region of the filtering part is formed to have micro-holes allowing the biomolecules having a predetermined size or smaller to pass therethrough, thereby preventing damage to the biomolecules during a process of separating the biomolecules included in the sample, reducing time and cost, improving the durability of the membrane structure body, and preventing the blockage of the membrane structure body, caused by substances excluding the biomolecules to be filtered, and degradation in filtering efficiency, caused thereby.

Description

technical field [0001] The present invention relates to a membrane structure having a matrix structure and a biomolecule filter using the same, and more specifically, to a membrane structure having a plurality of window units arranged in a matrix form and to filtering biomolecules contained in a sample using the same biomolecular filter. Background technique [0002] This application claims priority from Korean Patent Application No. 10-2018-0010006 filed on January 26, 2018, the entire contents of which are incorporated herein by reference. [0003] Generally, a biomolecule refers to a substance constituting a living body or a substance originating from a living body such as nucleic acid, protein, and microvesicle. Recently, it is known that exosomes (exosomes), which are intercellular signaling substances, can be used to diagnose diseases such as cancer and Alzheimer's, so interest and research on technologies that can effectively isolate specific biomolecules such as exo...
