| Outline of Final Research Achievements |
A new detection method was developed for detection of RNA at the single-molecule level. We foucused on that the charge transfer rate through DNA is strongly affected by the DNA sequence and chemical modification of nucleobases. The charge-transfer dynamics in DNA/RNA hybrid was measured as the length of the duration of the off time of blinking of the fluorescence. This enabled the detection of target sequence, allowing for sample sizes as small as 5 fmol (< 0.2 nM, 20 uL). The target can be analyzed under conditions of the automatic measurement of more than 100 samples within 3 h, which makes possible the high-throughput screening needed in RNA diagnosis.
