MICROFLUIDIC CHIP WITH MICROCHANNELS FILLED WITH NANOFIBERS AND ITS FABRICATION METHOD

摘要

The present invention relates to a microchannel biochip equipped with a microchannel unit filled with nanofibers and a method for producing the same. More specifically, the microchannel biochip includes a bottom plate and a top plate produced by being laminated on the top surface of the bottom plate. The top plate comprises: a microchannel unit formed in a tapered shape, in which the cross sectional shape thereof in a thickness direction is gradually widened, and consisting of a microchannel and a side end part of the end of the microchannel; and a chamber unit connected with the side end part and formed in a hole shape through which the top surface and bottom surface of the top plate pass. The side end part is formed in a shape which has a gradually increasing width from the microchannel to the chamber unit in order to be connected with the chamber unit. Also, polymer nanofibers are filled in all or a part of the microchannel unit. Nanofibers are filled in a microchannel which has not been indicated in existing biochips, and cells can be included in an environment similar to the inside of a human body, so that the movement of the cells can be three-dimensionally expanded.
