Our Research Themes (연구주제)

Our lab is mainly interested in (1) a microfluidic/nanofluidic device, essentially a network of micro/nanoscale fluidic components, and (2) application of microfluidic and nanofluidic device to analyze biomolecules such as proteins, peptide, RNA, and DNA, which are cruicial in assesing physilogical state of a human. We are also working on (3) individual microscale fluidic components including micropump, microvalve, micromixer, and microscale dialyzer, (4) novel microfabrication techniques such as micro 3D printing, laser machining, and hot embossing for plastic-based microfluidic/nanofluidic devices. Lastly, we are keen to explore (5) interesting micro/nanoscale physicochemical phenomena that are not observable in conventional macroscale fluidic systems including electrokinetics and microscale heat transfer. Ultimately, we are pursuing microanalytical systems or lab-on-a-chip (LOC) that can determine clinically and biologically important biomolecules accurately, rapidly, and reliably - so that they can replace bulky, expensive, material-consuming, but essential analytical instruments in research or clinical laboratory.


우리 연구실은 (1) 마이크로스케일의 유체기계 네트워크로 구성된 미소유체/나노유체 디바이스의 설계 및 제작, (2) 사람의 건강상태를 진단할 수 있는 단백질, 펩티드, DNA, RNA 등 생체분자를 분석하는데 있어서 미소유체/나노유체 디바이스의 응용분야, (3) 마이크로 펌프, 마이크로 밸브, 마이크로믹서, 마이크로투석기 등 다양한 마이크로스케일의 유체기계의 설계 및 제작, (4) 3D 프린팅, 레이저머시닝, 핫임보싱과 같은 플라스틱 기반의 첨단 마이크로가공기술에 주로 관심을 가지고 다양한 연구를 수행하고 있습니다. 또한 일반적인 스케일에서는 관찰할 수 없으나 마이크로스케일에서 관찰가능한 물리화학적 현상 예를 들어 전현상, 마이크로열전달 현상 등에 대한 연구도 같이 수행하고 있습니다. 궁극적으로는 이러한 요소기술을 기반으로 의학적으로 혹은 생물학적으로 중요한 생체분자를 정확, 신속, 안정적으로 검출할 수 있는 마이크로 스케일의 분석기기, 즉 랩온어칩(LOC)을 개발하여 현재 의학, 생물학, 약학, 생화학 등 다양한 분야에서 사용되는 고가의 부피가 크고 많은 시료를 소비하는 기존의 분석장비를 대체하고자 합니다.
