MEMBRANE MOBILE POLYMER MICROFLUIDIC CHIP AND PREPARATION METHOD OF SAME

WIPO Patent Application WO/2013/023448

A1

A membrane mobile polymer microfluidic chip and a preparation method of the same. The microfluidic chip comprises: a first substrate (100), a membrane (300), several structure parts (101) located on one surface of the first substrate (100), several first through holes (102) located on the first substrate (100), and a second substrate (200). One surface of the second substrate (200) is attached to the other surface of the first substrate (100), and the other surface of the second substrate (200) is smooth. The second substrate (200) is provided with a second through hole (201) corresponding to the first through hole (102) of the first substrate (100). The first through hole (102) and the second through hole (201) form an integral through hole (400). The membrane (300) is attached to the other surface of the second substrate (200). The preparation method comprises the following steps: disposing at least one fuse wire (103, 202) on welding surfaces of a first substrate (100) and a second substrate (200); and attaching the first substrate (100) to the second substrate (200) and fusing the fuse wire (103, 202) to welding the first substrate (100) to the second substrate (200), and after welding, attaching a membrane (300) to a surface of the second substrate (200).
