Abstract

We combined a microfluidic stretch of a single DNA molecule and a visualization technique with fluorescent gold nanoparticle labeling, which can be observed with fluorescence microscope and scanning electron microscope (SEM) for imaging of methylated site on a single DNA molecule. It will realize bimodal microscope imaging of methylated site and enhance the imaging resolution down to nanometer level toward epigenetic analysis on the basis of high-resolution mapping of methylation sites.
