    Detection of single-molecule DNA hybridization by using dual-color total internal reflection fluorescence microscopy

    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 ...
