미소유체 칩 상에서 Quantum Dot 및 마이크로 비드를 이용한 생체물질 분석

Microbead-based bio-assay using quantum dot fluorescence in a microfludic chip

초록

We present a microfluidic chip designed for the detection of antibody by using quantum dots fluorescence and a microbead-based assay. A custom designed PDMS microfluidic chip with multi-layer channel is utilized for capturing microbeads; antibody injection into each micro-well; QD injection; and fluorescence detection. The experiment using the fabricated microfluidic chip has been performed on solutions with various concentrations of antibody and has shown correlated fluorescent intensities.
