Outline of Final Research Achievements |
A novel process of nanowire formation was developed using metallization of DNA molecules, and electrical property of the fabricated nanowires was evaluated. First, a single DNA molecule was stretched and immobilized between two electrodes in a nanochannel, and a single nanowire was formed by DNA metallization. Next, we demonstrated that our technique permits double-stranded DNA molecules to be specifically metallized while not permitting metallization of single-stranded DNA molecules. Moreover, a novel technique for deoxyribonuclease (DNase) detection was developed using partially-metallized DNA nanowires. Also, we succeeded in extracting plasma from whole blood easily and rapidly using capillary force in a microchannel, and developed a method for detecting specific proteins in the extracted plasma.
