Abstract
We examined the use of prism-type simultaneous dual-color total internal reflection fluorescence microscopy (TIRFM) to probe DNA molecules at the single-molecule level. The system allowed the direct detection of the complementary interactions between single-stranded probe DNA molecules (16-mer) and various lengths of single-stranded target DNA molecules (16-mer and 55-mer) that had been labeled with different fluorescent dyes (Cy3, Cy5, and fluorescein). The polymer-modified glass substrate and the extent of DNA probe immobilization were easily characterized either with standard TIRFM or with atomic force microscopy. However, only dual-color TIRFM could provide unambiguous images of individual single-stranded target DNA molecules hybridized with the correct sequence in the range of fM–aM. Succinic anhydride showed low RMS roughness and was found to be an optimal blocking reagent against non-specific adsorption, with an efficiency of 92%. This study provides a benchmark for directly monitoring the interactions and the detection of co-localization of two different DNA molecules and can be applied to the development of a nanoarray biochip at the single-molecule level.
