Outline of Final Research Achievements

Novel flow-through PCR microfluidics system using vapor pressure of destabilizing-flow source was developed and achieved ultimately-rapid and small-volume DNA amplification on a chip. The yield of PCR amplification compared to the thermal cycler was shown about 80% in less than 15 minutes. The chip device was made of pressure-sensitive polyolefin film (PSP) and cyclo-olefin polymer (COP) substrate, which was processed with a micro-Numerical Control machine to produce a microchannel. The enclosed structure of the microchannel was fabricated solely by weighting PSP film on COP, resulting in a practical application that excels when compared with other devices. For automatic-mixing on a single chip, pillar structures were constructed in a reaction chamber. Droplets of reagents were captured among these pillars by surface tension. When the sample solution was loaded into the chamber, the reagents were mixed and then flowed to the opposite side of microchannel.
