METHOD FOR FORMING MICROCHANNELS OF LAB-ON-A-CHIP

摘要

A method to form a microchannel for a lab-on-a-chip without photolithography is disclosed. The method to form a microchannel for a lab-on-a-chip without photolithography according to an embodiment of the present invention comprises: a step a) of forming a first channel pattern having a semicircular cross section on a first thermoplastic substrate to be engraved; a step b) of stacking a second flat thermoplastic substrate on the first thermoplastic substrate and forms the first channel pattern on the surface of the second thermoplastic substrate to be embossed through the hot-embossing of the stacked body; a step c) of dismantling the stacked body after the stacked body is cooled and transcribing the embossed first channel pattern formed by using the second thermoplastic substrate as a mold into a polydimethylsiloxane substrate; and a step d) of bonding a pair of polydimethylsiloxane substrates obtained by repetitively performing the step c) to each other to allow the surfaces of the polydimethylsiloxane substrates where the first channel patterns are formed to face each other.
