초록

본 논문은 다기능 미소유체시스템의 일체형 패키징을 위한 MSI (microfluidic system interface) 기술을 제안하고, 이를 설계, 제작, 시험 평가하였다. MSI 기술을 통해 플러그 방식의 유체 인터커넥터, 유체제어를 위한 미소밸브, 광학 인터페이스를 위한 광학창을 유체시스템에 일체형으로 쉽게 구현할 수 있었다. MSI 기술의 유용성을 보이기 위해 미소 유전자시료전처리시스템에 적용되었으며, 미소 유전자시료전처리시스템은 세포정제, 세포분리, 세포용해, DNA 고체상추출, 중합효소연쇄반응, 그리고 모세관전기영동 기능으로 구성되었다. 나아가 MSI 기술이 적용된 미소 유전자시료전처리시스템의 DNA 고체상추출 및 중합효소연쇄반응의 실험결과로부터 MSI가 미소유체시스템을 위한 실용적 패키징 기술임이 검증되었다.

This paper presents the technology for the design, fabrication, and characterization of a microfluidic system interface (MSI); the purpose of this technology is to enable the integration of complex microfluidic systems. The MSI technology can be applied in a simple manner for realizing complex arrangements of microfluidic interconnects, integrated microvalves for fluid control, and optical windows for on-chip optical processes. A microfluidic system for the preparation of genetic samples was used as the test vehicle to prove the effectiveness of the MSI technology for packaging complex microfluidic systems with multiple functionalities. The miniaturized genetic sample preparation system comprised several functional compartments, including compartments for cell purification, cell separation, cell lysis, solid-phase DNA extraction, polymerase chain reaction, and capillary electrophoresis. Additionally, the functional operation of the solid-phase extraction and PCR thermocycling compartments was demonstrated by using the MSI.
