| Outline of Final Research Achievements |
Image analysis of methylated DNA has a great potential for exploring epigenomic change in cancer cells. In order to visualize signal variation caused by DNA methylation, it is crucial that the DNA molecules are arrayed in parallel direction inside the narrow microscopic field. Here we show that methylated DNA molecules can be trapped and stretched at the patterned grooves on the surface of microfluidic channel by flow. The demonstrated DNA aligning technique enables simultaneous molecular imaging and detection for cancer diagnosis at the single molecule level.
